Bugfix: Make `backup` and `tag` commands separate tags by comma
Running `restic backup --tag foo,bar` previously created snapshots with one
single tag containing a comma (`foo,bar`) instead of two tags (`foo`, `bar`).
Similarly, the `tag` command's `--set`, `--add` and `--remove` options would
treat `foo,bar` as one tag instead of two tags. This was inconsistent with
other commands and often unexpected when one intended `foo,bar` to mean two
tags.
To be consistent in all commands, restic now interprets `foo,bar` to mean two
separate tags (`foo` and `bar`) instead of one tag (`foo,bar`) everywhere,
including in the `backup` and `tag` commands.
NOTE: This change might result in unexpected behavior in cases where you use
the `forget` command and filter on tags like `foo,bar`. Snapshots previously
backed up with `--tag foo,bar` will still not match that filter, but snapshots
saved from now on will match that filter.
To replace `foo,bar` tags with `foo` and `bar` tags in old snapshots, you can
first generate a list of the relevant snapshots using a command like:
restic snapshots --json --quiet | jq '.[] | select(contains({tags: ["foo,bar"]})) | .id'
and then use `restic tag --set foo --set bar snapshotID [...]` to set the new
tags. Please adjust the commands to include real tag names and any additional
tags, as well as the list of snapshots to process.
