# For "rear mkbackup" and also in particular for "rear mkrescue" # ( also the latter because for most external backup methods only "rear mkrescue" # is used because most external backup methods do not implement making a backup # but only implement to restore a backup see 'BACKUP SOFTWARE INTEGRATION' in "man rear" ) # check that the BACKUP method implements a matching backup restore method # i.e. check that a usr/share/rear/restore/$BACKUP directory exists # and error out when a BACKUP method seems to not support a backup restore # to ensure that the user cannot specify a non-working BACKUP in /etc/rear/local.conf # see https://github.com/rear/rear/issues/914 # and https://github.com/rear/rear/issues/159 # and https://github.com/rear/rear/issues/2337#issuecomment-596471615 # and https://github.com/rear/rear/issues/2351 if ! test -d "$SHARE_DIR/restore/$BACKUP" ; then Error "The BACKUP method '$BACKUP' is not supported (no $SHARE_DIR/restore/$BACKUP directory)" fi
