## SYNOPSIS
`zvault remove <BACKUP>`
`zvault remove [OPTIONS] <BACKUP>`
## DESCRIPTION
@ -17,6 +17,9 @@ If `repository` is omitted, the default repository location is used instead.
If a backup is referenced, this backup will be deleted. If a subtree is given,
the backup is instead rewritten to not include that subtree anymore.
If a folder of backups is referenced by `BACKUP` the flag `--force` must be set
in order to remove all backups in that folder (also recursively).
Note: When removing backup subtrees, the meta information of that backup is left
unchanged and still contains the data (e.g. duration and size) of the original
backup run.
@ -32,6 +35,11 @@ data of the deleted backups becomes inaccessible and can not be restored.**
## OPTIONS
* `-f`, `--force`:
Remove multiple backups in a backup folder
* `-h`, `--help`:
Prints help information
