Tape backup to select specific folder from datastore

[mdarwish]

Hi All

I'm trying to take backup to tape using regex to take backup for a specific folder not the entire host
the available filter option is through Group Filter as per the below picture
for example If I choose Regex then past the select folder on it
but it seems the filter is not working and show 0 selected group once I run the backup

how would it be possible to take backup for selected items only?

TLDR: Use the --backup-id option when invoking proxmox-backup-client.

See Terminology for Backup Type, ID, Group and Snapshot:

• Type: Options are only "vm", "ct" and "host"
• ID: "host type backups normally use the hostname." -> This is the "storage-2" part that you see
• Group: <type>/<id> -> type is "host"
• Snapshot: <type>/<ID>/<time>

The Regex only matches against the group, i.e., <type>/<id>. So if you specify a custom ID using proxmox-backup-client --backup-id id_for_my_backup, then they are put into individual groups, letting you select them using the Regex.

$ man proxmox-backup-client
...
       --backup-id <string>
              Backup ID.

Giving the backups individual IDs has the additional benefit that you can see them in the Tape inventory; so you can find out what contents of a specific host a tape contains without loading its data back into the datastore, where you can see the created archive files.
