export-tar: just msgpack and b64encode all item metadata and
put that into a BORG specific PAX header.
this is *additional* to the standard tar metadata.
import-tar: when detecting the BORG specific PAX header, just get
all metadata from there (and ignore the standard tar
metadata).

Examples

~~~~~~~~
|
|
::

|
|
|
# export as uncompressed tar

|
|
# exclude some file types, compress using gzip
|
|
$ borg export-tar /path/to/repo::Monday Monday.tar.gz --exclude '*.so'
|
|
|
|
# use higher compression level with gzip
|
|
$ borg export-tar --tar-filter="gzip -9" repo::Monday Monday.tar.gz

# copy an archive from repoA to repoB
|
|
$ borg export-tar --tar-format=BORG repoA::archive - | borg import-tar repoB::archive -
|
|
|
|
# export a tar, but instead of storing it on disk, upload it to remote site using curl
|
|
$ borg export-tar /path/to/repo::Monday - | curl --data-binary @- https://somewhere/to/POST

# remote extraction via "tarpipe"

Archives transfer script
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Outputs a script that copies all archives from repo1 to repo2:
|
|
|
|
::
|
|
|
|
for A T in `borg list --format='{archive} {time:%Y-%m-%dT%H:%M:%S}{LF}' repo1`
|
|
do
|
|
echo "borg export-tar --tar-format=BORG repo1::$A - | borg import-tar --timestamp=$T repo2::$A -"
|
|
done
|
|
|
|
Kept:
|
|
|
|
- archive name, archive timestamp
|
|
- archive contents (all items with metadata and data)
|
|
|
|
Lost:
|
|
|
|
- some archive metadata (like the original commandline, execution time, etc.)
|
|
|
|
Please note:
|
|
|
|
- all data goes over that pipe, again and again for every archive
|
|
- the pipe is dumb, there is no data or transfer time reduction there due to deduplication
|
|
- maybe add compression
|
|
- pipe over ssh for remote transfer
|
|
- no special sparse file support
