borgbackup 2.x migration notes
==============================
This borg 2.x package contains a beta release. As such it may still break
compatibility with the final 2.0 release your backups may become incompatible
with the actual borg 2.0 release.
borg 2.x is incompatible with borg 1.x. This affects both the interface and the
repository format. For instance `borg init` has become `borg repo-create`. The only
thing borg 2.x can do with a borg 1.x repository or borg 1.x serve is read.
Thus, repositories must be upgraded to the borg 2.x repository format using
`borg transfer` which copies the contents. For Debian, borg 1.x and borg 2.x
are packaged in a coinstallable way such that borg 2.x is available as the
`borg2` command.
Thus borg 1.x and borg 2.x are packaged in a coinstallable way. If you upgrade
from an earlier release, the `borgbackup` package continues to be borg 1.x. You
can additionally install `borgbackup2` and initiate the migration using `borg2`
commands. Once you are confident, you can install `borgbackup-is-borgbackup2`
to turn the unversiond borg command into version 2.x. This will remove borg 1.x
and all reverse dependencies that are not compatible with borg 2.x. Please use
the bookworm cycle to remove your usage of borg 1.x as it shall not be part of
trixie.
Users of `borgbackup2` that interact with a server lacking
`borgbackup-is-borgbackup2` should pass `--remote-path=borg2`. The name of the
borg binary can be different for cloud storage providers.
