Command to run before backup
If set, the command or script entered will be run as root before
the backup is run on schedule. This can be useful for mounting removable
or remote filesystems to which the backup should be written.
If the command fails (with a non-zero exit status), the rest of the backup
will not proceed.
The command can discover information about the backup via environment variables
starting with BACKUP_ , like:
- BACKUP_DOMAIN_NAMES
- Names of all the virtual servers being backed up.
- BACKUP_DEST
- The destination directory or URL.
- BACKUP_FEATURES
- Names of all Virtualmin features included in the backup. If BACKUP_ALL is set to 1, all features are included.
