A tool to help convert a borg repository to restic.
It assumes the following environment variables to be set:
BORG_REPO
set to the old borg repositoryRESTIC_REPOSITORY
set to the restic repository
It is highly recommended to also set BORG_PASSPHRASE
(or BORG_PASSCOMMAND
),
and RESTIC_PASSWORD[_FILE]
to allow non-interactive access to the two repositories.
It will mount the borg repository, collect a list of all snapshots, and will invoke restic to "back up from the mountpoint".
It does this by changing the working directory of the restic process to the location of the mounted borg contents (and an optional subpath in there).
Additionally, the path shown in restic snapshots
can be overridden, so it
doesn't show artifacts from the conversion.
This needs the version of restic
in $PATH
to have
restic/restic#3200 applied.
Timestamps are preserved (to the best of my knowledge). It's also possible to
explicitly set the hostname for the restic backup
command.
Check the --help
output for more help.
