borg [common options] with-lock [options] COMMAND [ARGS...]
command to run
This command runs a user-specified command while locking the repository. For example:
$ BORG_REPO=/mnt/borgrepo borg with-lock rsync -av /mnt/borgrepo /somewhere/else/borgrepo
It will first try to acquire the lock (make sure that no other operation is running in the repo), then execute the given command as a subprocess and wait for its termination, release the lock and return the user command’s return code as borg’s return code.
If you copy a repository with the lock held, the lock will be present in the copy. Thus, before using borg on the copy from a different host, you need to use “borg break-lock” on the copied repository, because Borg is cautious and does not automatically remove stale locks made by a different host.
borg [common options] break-lock [options]
This command breaks the repository and cache locks. Please use carefully and only while no borg process (on any machine) is trying to access the Cache or the Repository.
