Changelog for restic 0.8.1 (2017-12-27) ======================================= The following sections list the changes in restic 0.8.1 relevant to restic users. The changes are ordered by importance. Summary ------- * Fix #1457: Improve s3 backend with DigitalOcean Spaces * Fix #1454: Correct cache dir location for Windows and Darwin * Fix #1459: Disable handling SIGPIPE * Chg #1452: Do not save atime by default * Enh #1436: Add code to detect old cache directories * Enh #1439: Improve cancellation logic * Enh #11: Add the `diff` command Details ------- * Bugfix #1457: Improve s3 backend with DigitalOcean Spaces https://github.com/restic/restic/issues/1457 https://github.com/restic/restic/pull/1459 * Bugfix #1454: Correct cache dir location for Windows and Darwin The cache directory on Windows and Darwin was not correct, instead the directory `.cache` was used. https://github.com/restic/restic/pull/1454 * Bugfix #1459: Disable handling SIGPIPE We've disabled handling SIGPIPE again. Turns out, writing to broken TCP connections also raised SIGPIPE, so restic exits on the first write to a broken connection. Instead, restic should retry the request. https://github.com/restic/restic/issues/1457 https://github.com/restic/restic/issues/1466 https://github.com/restic/restic/pull/1459 * Change #1452: Do not save atime by default By default, the access time for files and dirs is not saved any more. It is not possible to reliably disable updating the access time during a backup, so for the next backup the access time is different again. This means a lot of metadata is saved. If you want to save the access time anyway, pass `--with-atime` to the `backup` command. https://github.com/restic/restic/pull/1452 * Enhancement #1436: Add code to detect old cache directories We've added code to detect old cache directories of repositories that haven't been used in a long time, restic now prints a note when it detects that such dirs exist. Also, the option `--cleanup-cache` was added to automatically remove such directories. That's not a problem because the cache will be rebuild once a repo is accessed again. https://github.com/restic/restic/pull/1436 * Enhancement #1439: Improve cancellation logic The cancellation logic was improved, restic can now shut down cleanly when requested to do so (e.g. via ctrl+c). https://github.com/restic/restic/pull/1439 * Enhancement #11: Add the `diff` command The command `diff` was added, it allows comparing two snapshots and listing all differences. https://github.com/restic/restic/issues/11 https://github.com/restic/restic/issues/1460 https://github.com/restic/restic/pull/1462 Changelog for restic 0.8.0 (2017-11-26) ======================================= The following sections list the changes in restic 0.8.0 relevant to restic users. The changes are ordered by importance. Summary ------- * Sec #1445: Prevent writing outside the target directory during restore * Fix #1256: Re-enable workaround for S3 backend * Fix #1291: Reuse backend TCP connections to BackBlaze B2 * Fix #1317: Run prune when `forget --prune` is called with just snapshot IDs * Fix #1437: Remove implicit path `/restic` for the s3 backend * Enh #1102: Add subdirectory `ids` to fuse mount * Enh #1114: Add `--cacert` to specify TLS certificates to check against * Enh #1216: Add upload/download limiting * Enh #1271: Cache results for excludes for `backup` * Enh #1274: Add `generate` command, replaces `manpage` and `autocomplete` * Enh #1367: Allow comments in files read from via `--file-from` * Enh #448: Sftp backend prompts for password * Enh #510: Add `dump` command * Enh #1040: Add local metadata cache * Enh #1249: Add `latest` symlink in fuse mount * Enh #1269: Add `--compact` to `forget` command * Enh #1281: Google Cloud Storage backend needs less permissions * Enh #1319: Make `check` print `no errors found` explicitly * Enh #1353: Retry failed backend requests Details ------- * Security #1445: Prevent writing outside the target directory during restore A vulnerability was found in the restic restorer, which allowed attackers in special circumstances to restore files to a location outside of the target directory. Due to the circumstances we estimate this to be a low-risk vulnerability, but urge all users to upgrade to the latest version of restic. Exploiting the vulnerability requires a Linux/Unix system which saves backups via restic and a Windows systems which restores files from the repo. In addition, the attackers need to be able to create create files with arbitrary names which are then saved to the restic repo. For example, by creating a file named "..\test.txt" (which is a perfectly legal filename on Linux) and restoring a snapshot containing this file on Windows, it would be written to the parent of the target directory. We'd like to thank Tyler Spivey for reporting this responsibly! https://github.com/restic/restic/pull/1445 * Bugfix #1256: Re-enable workaround for S3 backend We've re-enabled a workaround for `minio-go` (the library we're using to access s3 backends), this reduces memory usage. https://github.com/restic/restic/issues/1256 https://github.com/restic/restic/pull/1267 * Bugfix #1291: Reuse backend TCP connections to BackBlaze B2 A bug was discovered in the library we're using to access Backblaze, it now reuses already established TCP connections which should be a lot faster and not cause network failures any more. https://github.com/restic/restic/issues/1291 https://github.com/restic/restic/pull/1301 * Bugfix #1317: Run prune when `forget --prune` is called with just snapshot IDs A bug in the `forget` command caused `prune` not to be run when `--prune` was specified without a policy, e.g. when only snapshot IDs that should be forgotten are listed manually. https://github.com/restic/restic/pull/1317 * Bugfix #1437: Remove implicit path `/restic` for the s3 backend The s3 backend used the subdir `restic` within a bucket if no explicit path after the bucket name was specified. Since this version, restic does not use this default path any more. If you created a repo on s3 in a bucket without specifying a path within the bucket, you need to add `/restic` at the end of the repository specification to access your repo: `s3:s3.amazonaws.com/bucket/restic` https://github.com/restic/restic/issues/1292 https://github.com/restic/restic/pull/1437 * Enhancement #1102: Add subdirectory `ids` to fuse mount The fuse mount now has an `ids` subdirectory which contains the snapshots below their (short) IDs. https://github.com/restic/restic/issues/1102 https://github.com/restic/restic/pull/1299 https://github.com/restic/restic/pull/1320 * Enhancement #1114: Add `--cacert` to specify TLS certificates to check against We've added the `--cacert` option which can be used to pass one (or more) CA certificates to restic. These are used in addition to the system CA certificates to verify HTTPS certificates (e.g. for the REST backend). https://github.com/restic/restic/issues/1114 https://github.com/restic/restic/pull/1276 * Enhancement #1216: Add upload/download limiting We've added support for rate limiting through `--limit-upload` and `--limit-download` flags. https://github.com/restic/restic/issues/1216 https://github.com/restic/restic/pull/1336 https://github.com/restic/restic/pull/1358 * Enhancement #1271: Cache results for excludes for `backup` The `backup` command now caches the result of excludes for a directory. https://github.com/restic/restic/issues/1271 https://github.com/restic/restic/pull/1326 * Enhancement #1274: Add `generate` command, replaces `manpage` and `autocomplete` The `generate` command has been added, which replaces the now removed commands `manpage` and `autocomplete`. This release of restic contains the most recent manpages in `doc/man` and the auto-completion files for bash and zsh in `doc/bash-completion.sh` and `doc/zsh-completion.zsh` https://github.com/restic/restic/issues/1274 https://github.com/restic/restic/pull/1282 * Enhancement #1367: Allow comments in files read from via `--file-from` When the list of files/dirs to be saved is read from a file with `--files-from`, comment lines (starting with `#`) are now ignored. https://github.com/restic/restic/issues/1367 https://github.com/restic/restic/pull/1368 * Enhancement #448: Sftp backend prompts for password The sftp backend now prompts for the password if a password is necessary for login. https://github.com/restic/restic/issues/448 https://github.com/restic/restic/pull/1270 * Enhancement #510: Add `dump` command We've added the `dump` command which prints a file from a snapshot to stdout. This can e.g. be used to restore files read with `backup --stdin`. https://github.com/restic/restic/issues/510 https://github.com/restic/restic/pull/1346 * Enhancement #1040: Add local metadata cache We've added a local cache for metadata so that restic doesn't need to load all metadata (snapshots, indexes, ...) from the repo each time it starts. By default the cache is active, but there's a new global option `--no-cache` that can be used to disable the cache. By deafult, the cache a standard cache folder for the OS, which can be overridden with `--cache-dir`. The cache will automatically populate, indexes and snapshots are saved as they are loaded. Cache directories for repos that haven't been used recently can automatically be removed by restic with the `--cleanup-cache` option. A related change was to by default create pack files in the repo that contain either data or metadata, not both mixed together. This allows easy caching of only the metadata files. The next run of `restic prune` will untangle mixed files automatically. https://github.com/restic/restic/issues/29 https://github.com/restic/restic/issues/738 https://github.com/restic/restic/issues/282 https://github.com/restic/restic/pull/1040 https://github.com/restic/restic/pull/1287 https://github.com/restic/restic/pull/1436 https://github.com/restic/restic/pull/1265 * Enhancement #1249: Add `latest` symlink in fuse mount The directory structure in the fuse mount now exposes a symlink `latest` which points to the latest snapshot in that particular directory. https://github.com/restic/restic/pull/1249 * Enhancement #1269: Add `--compact` to `forget` command The option `--compact` was added to the `forget` command to provide the same compact view as the `snapshots` command. https://github.com/restic/restic/pull/1269 * Enhancement #1281: Google Cloud Storage backend needs less permissions The Google Cloud Storage backend no longer requires the service account to have the `storage.buckets.get` permission ("Storage Admin" role) in `restic init` if the bucket already exists. https://github.com/restic/restic/pull/1281 * Enhancement #1319: Make `check` print `no errors found` explicitly The `check` command now explicetly prints `No errors were found` when no errors could be found. https://github.com/restic/restic/issues/1303 https://github.com/restic/restic/pull/1319 * Enhancement #1353: Retry failed backend requests https://github.com/restic/restic/pull/1353 Changelog for restic 0.7.3 (2017-09-20) ======================================= The following sections list the changes in restic 0.7.3 relevant to restic users. The changes are ordered by importance. Summary ------- * Fix #1246: List all files stored in Google Cloud Storage Details ------- * Bugfix #1246: List all files stored in Google Cloud Storage For large backups stored in Google Cloud Storage, the `prune` command fails because listing only returns the first 1000 files. This has been corrected, no data is lost in the process. In addition, a plausibility check was added to `prune`. https://github.com/restic/restic/issues/1246 https://github.com/restic/restic/pull/1247 Changelog for restic 0.7.2 (2017-09-13) ======================================= The following sections list the changes in restic 0.7.2 relevant to restic users. The changes are ordered by importance. Summary ------- * Fix #1167: Do not create a local repo unless `init` is used * Fix #1164: Make the `key remove` command behave as documented * Fix #1191: Make sure to write profiling files on interrupt * Enh #1132: Make `key` command always prompt for a password * Enh #1179: Resolve name conflicts, append a counter * Enh #1218: Add `--compact` to `snapshots` command * Enh #317: Add `--exclude-caches` and `--exclude-if-present` * Enh #697: Automatically generate man pages for all restic commands * Enh #1044: Improve `restore`, do not traverse/load excluded directories * Enh #1061: Add Dockerfile and official Docker image * Enh #1126: Use the standard Go git repository layout, use `dep` for vendoring * Enh #1134: Add support for storing backups on Google Cloud Storage * Enh #1144: Properly report errors when reading files with exclude patterns. * Enh #1149: Add support for storing backups on Microsoft Azure Blob Storage * Enh #1196: Add `--group-by` to `forget` command for flexible grouping * Enh #1203: Print stats on all BSD systems when SIGINFO (ctrl+t) is received * Enh #1205: Allow specifying time/date for a backup with `--time` Details ------- * Bugfix #1167: Do not create a local repo unless `init` is used When a restic command other than `init` is used with a local repository and the repository directory does not exist, restic creates the directory structure. That's an error, only the `init` command should create the dir. https://github.com/restic/restic/issues/1167 https://github.com/restic/restic/pull/1182 * Bugfix #1164: Make the `key remove` command behave as documented https://github.com/restic/restic/pull/1164 * Bugfix #1191: Make sure to write profiling files on interrupt Since a few releases restic had the ability to write profiling files for memory and CPU usage when `debug` is enabled. It was discovered that when restic is interrupted (ctrl+c is pressed), the proper shutdown hook is not run. This is now corrected. https://github.com/restic/restic/pull/1191 * Enhancement #1132: Make `key` command always prompt for a password The `key` command now prompts for a password even if the original password to access a repo has been specified via the `RESTIC_PASSWORD` environment variable or a password file. https://github.com/restic/restic/issues/1132 https://github.com/restic/restic/pull/1133 * Enhancement #1179: Resolve name conflicts, append a counter https://github.com/restic/restic/issues/1179 https://github.com/restic/restic/pull/1209 * Enhancement #1218: Add `--compact` to `snapshots` command The option `--compact` was added to the `snapshots` command to get a better overview of the snapshots in a repo. It limits each snapshot to a single line. https://github.com/restic/restic/issues/1218 https://github.com/restic/restic/pull/1223 * Enhancement #317: Add `--exclude-caches` and `--exclude-if-present` A new option `--exclude-caches` was added that allows excluding cache directories (that are tagged as such). This is a special case of a more generic option `--exclude-if-present` which excludes a directory if a file with a specific name (and contents) is present. https://github.com/restic/restic/issues/317 https://github.com/restic/restic/pull/1170 https://github.com/restic/restic/pull/1224 * Enhancement #697: Automatically generate man pages for all restic commands https://github.com/restic/restic/issues/697 https://github.com/restic/restic/pull/1147 * Enhancement #1044: Improve `restore`, do not traverse/load excluded directories https://github.com/restic/restic/pull/1044 * Enhancement #1061: Add Dockerfile and official Docker image https://github.com/restic/restic/pull/1061 * Enhancement #1126: Use the standard Go git repository layout, use `dep` for vendoring The git repository layout was changed to resemble the layout typically used in Go projects, we're not using `gb` for building restic any more and vendoring the dependencies is now taken care of by `dep`. https://github.com/restic/restic/pull/1126 * Enhancement #1134: Add support for storing backups on Google Cloud Storage https://github.com/restic/restic/issues/211 https://github.com/restic/restic/pull/1134 https://github.com/restic/restic/pull/1052 * Enhancement #1144: Properly report errors when reading files with exclude patterns. https://github.com/restic/restic/pull/1144 * Enhancement #1149: Add support for storing backups on Microsoft Azure Blob Storage The library we're using to access the service requires Go 1.8, so restic now needs at least Go 1.8. https://github.com/restic/restic/issues/609 https://github.com/restic/restic/pull/1149 https://github.com/restic/restic/pull/1059 * Enhancement #1196: Add `--group-by` to `forget` command for flexible grouping https://github.com/restic/restic/pull/1196 * Enhancement #1203: Print stats on all BSD systems when SIGINFO (ctrl+t) is received https://github.com/restic/restic/pull/1203 https://github.com/restic/restic/pull/1082 * Enhancement #1205: Allow specifying time/date for a backup with `--time` https://github.com/restic/restic/pull/1205 Changelog for restic 0.7.1 (2017-07-22) ======================================= The following sections list the changes in restic 0.7.1 relevant to restic users. The changes are ordered by importance. Summary ------- * Fix #1115: Fix `prune`, only include existing files in indexes * Enh #1055: Create subdirs below `data/` for local/sftp backends * Enh #1067: Allow loading credentials for s3 from IAM * Enh #1073: Add `migrate` cmd to migrate from `s3legacy` to `default` layout * Enh #1081: Clarify semantic for `--tasg` for the `forget` command * Enh #1080: Ignore chmod() errors on filesystems which do not support it * Enh #1082: Print stats on SIGINFO on Darwin and FreeBSD (ctrl+t) Details ------- * Bugfix #1115: Fix `prune`, only include existing files in indexes A bug was found (and corrected) in the index rebuilding after prune, which led to indexes which include blobs that were not present in the repo any more. There were already checks in place which detected this situation and aborted with an error message. A new run of either `prune` or `rebuild-index` corrected the index files. This is now fixed and a test has been added to detect this. https://github.com/restic/restic/pull/1115 * Enhancement #1055: Create subdirs below `data/` for local/sftp backends The local and sftp backends now create the subdirs below `data/` on open/init. This way, restic makes sure that they always exist. This is connected to an issue for the sftp server: https://github.com/restic/restic/issues/1055 https://github.com/restic/restic/pull/1077 https://github.com/restic/restic/pull/1105 https://github.com/restic/rest-server/pull/11#issuecomment-309879710 * Enhancement #1067: Allow loading credentials for s3 from IAM When no S3 credentials are specified in the environment variables, restic now tries to load credentials from an IAM instance profile when the s3 backend is used. https://github.com/restic/restic/issues/1067 https://github.com/restic/restic/pull/1086 * Enhancement #1073: Add `migrate` cmd to migrate from `s3legacy` to `default` layout The `migrate` command for chaning the `s3legacy` layout to the `default` layout for s3 backends has been improved: It can now be restarted with `restic migrate --force s3_layout` and automatically retries operations on error. https://github.com/restic/restic/issues/1073 https://github.com/restic/restic/pull/1075 * Enhancement #1081: Clarify semantic for `--tasg` for the `forget` command https://github.com/restic/restic/issues/1081 https://github.com/restic/restic/pull/1090 * Enhancement #1080: Ignore chmod() errors on filesystems which do not support it https://github.com/restic/restic/pull/1080 https://github.com/restic/restic/pull/1112 * Enhancement #1082: Print stats on SIGINFO on Darwin and FreeBSD (ctrl+t) https://github.com/restic/restic/pull/1082 Changelog for restic 0.7.0 (2017-07-01) ======================================= The following sections list the changes in restic 0.7.0 relevant to restic users. The changes are ordered by importance. Summary ------- * Fix #1013: Switch back to using the high-level minio-go API for s3 * Fix #965: Switch to `default` repo layout for the s3 backend * Enh #1021: Detect invalid backend name and print error * Enh #1029: Remove invalid pack files when `prune` is run * Enh #512: Add Backblaze B2 backend * Enh #636: Add dirs `tags` and `hosts` to fuse mount * Enh #989: Improve performance of the `find` command * Enh #975: Add new backend for OpenStack Swift * Enh #998: Improve performance of the fuse mount Details ------- * Bugfix #1013: Switch back to using the high-level minio-go API for s3 For the s3 backend we're back to using the high-level API the s3 client library for uploading data, a few users reported dropped connections (which the library will automatically retry now). https://github.com/restic/restic/issues/1013 https://github.com/restic/restic/issues/1023 https://github.com/restic/restic/pull/1025 * Bugfix #965: Switch to `default` repo layout for the s3 backend The default layout for the s3 backend is now `default` (instead of `s3legacy`). Also, there's a new `migrate` command to convert an existing repo, it can be run like this: `restic migrate s3_layout` https://github.com/restic/restic/issues/965 https://github.com/restic/restic/pull/1004 * Enhancement #1021: Detect invalid backend name and print error Restic now tries to detect when an invalid/unknown backend is used and returns an error message. https://github.com/restic/restic/issues/1021 https://github.com/restic/restic/pull/1070 * Enhancement #1029: Remove invalid pack files when `prune` is run The `prune` command has been improved and will now remove invalid pack files, for example files that have not been uploaded completely because a backup was interrupted. https://github.com/restic/restic/issues/1029 https://github.com/restic/restic/pull/1036 * Enhancement #512: Add Backblaze B2 backend https://github.com/restic/restic/issues/512 https://github.com/restic/restic/pull/978 * Enhancement #636: Add dirs `tags` and `hosts` to fuse mount The fuse mount now has two more directories: `tags` contains a subdir for each tag, which in turn contains only the snapshots that have this tag. The subdir `hosts` contains a subdir for each host that has a snapshot, and the subdir contains the snapshots for that host. https://github.com/restic/restic/issues/636 https://github.com/restic/restic/pull/1050 * Enhancement #989: Improve performance of the `find` command Improved performance for the `find` command: Restic recognizes paths it has already checked for the files in question, so the number of backend requests is reduced a lot. https://github.com/restic/restic/issues/989 https://github.com/restic/restic/pull/993 * Enhancement #975: Add new backend for OpenStack Swift https://github.com/restic/restic/pull/975 https://github.com/restic/restic/pull/648 * Enhancement #998: Improve performance of the fuse mount Listing directories which contain large files now is significantly faster. https://github.com/restic/restic/pull/998 Changelog for restic 0.6.1 (2017-06-01) ======================================= The following sections list the changes in restic 0.6.1 relevant to restic users. The changes are ordered by importance. Summary ------- * Enh #985: Allow multiple parallel idle HTTP connections * Enh #981: Remove temporary path from binary in `build.go` * Enh #974: Remove regular status reports Details ------- * Enhancement #985: Allow multiple parallel idle HTTP connections Backends based on HTTP now allow several idle connections in parallel. This is especially important for the REST backend, which (when used with a local server) may create a lot connections and exhaust available ports quickly. https://github.com/restic/restic/issues/985 https://github.com/restic/restic/pull/986 * Enhancement #981: Remove temporary path from binary in `build.go` The `build.go` now strips the temporary directory used for compilation from the binary. This is the first step in enabling reproducible builds. https://github.com/restic/restic/pull/981 * Enhancement #974: Remove regular status reports Regular status report: We've removed the status report that was printed every 10 seconds when restic is run non-interactively. You can still force reporting the current status by sending a `USR1` signal to the process. https://github.com/restic/restic/pull/974 Changelog for restic 0.6.0 (2017-05-29) ======================================= The following sections list the changes in restic 0.6.0 relevant to restic users. The changes are ordered by importance. Summary ------- * Enh #957: Make `forget` consistent * Enh #966: Unify repository layout for all backends * Enh #962: Improve memory and runtime for the s3 backend Details ------- * Enhancement #957: Make `forget` consistent The `forget` command was corrected to be more consistent in which snapshots are to be forgotten. It is possible that the new code removes more snapshots than before, so please review what would be deleted by using the `--dry-run` option. https://github.com/restic/restic/issues/953 https://github.com/restic/restic/pull/957 * Enhancement #966: Unify repository layout for all backends Up to now the s3 backend used a special repository layout. We've decided to unify the repository layout and implemented the default layout also for the s3 backend. For creating a new repository on s3 with the default layout, use `restic -o s3.layout=default init`. For further commands the option is not necessary any more, restic will automatically detect the correct layout to use. A future version will switch to the default layout for new repositories. https://github.com/restic/restic/issues/965 https://github.com/restic/restic/pull/966 * Enhancement #962: Improve memory and runtime for the s3 backend We've updated the library used for accessing s3, switched to using a lower level API and added caching for some requests. This lead to a decrease in memory usage and a great speedup. In addition, we added benchmark functions for all backends, so we can track improvements over time. The Continuous Integration test service we're using (Travis) now runs the s3 backend tests not only against a Minio server, but also against the Amazon s3 live service, so we should be notified of any regressions much sooner. https://github.com/restic/restic/pull/962 https://github.com/restic/restic/pull/960 https://github.com/restic/restic/pull/946 https://github.com/restic/restic/pull/938 https://github.com/restic/restic/pull/883
