Hi folks,

I just set up my Proxmox server on a Zimaboard 832 this weekend. I am working on creating scheduled backups for my drives. I have 3 storage drives attached to my Zimaboard. Proxmox is on a 240Gb SSD (sda) and my VMs & LXCs are on a 500Gb SSD (sdb) and I have my ISO images stored on a 256Gb USB drive (sdc) plugged into one of the two USB ports of the Zimaboard. I was able to set up an NFS share folder on my Synology NAS and added it to Proxmox as a shared storage drive. To test it I installed Pihole using an LXC from PVE Helper-Scripts. After some troubleshooting I was able to backup the Pihole container to my NAS.

I want to back up my ISO images too just in case the USB drive is accidentally removed while still mounted. The USB drive is configured as a directory using an ext4 partition. I went through the PVE 9.0 Administrators Guide and looked online for an answer on how to backup the USB to my NAS but I can't find anything. The storage drive display shows that backups must be possible (see pic). But I can't figure out how to create a scheduled backup from the Datacenter tab. Is there a way to create a scheduled backup of my USB drive? What am I missing?? Thanks !!!!

Figured it out.
SOLVED: To backup an attached drive that you created as a file "Directory" for storing ISO used to create your VMs you need to:
1. Go to Datacenter > Permissions > Pools and click "Create" to add a pool.
2. Name the pool and add a comment like "backs up my ISO storage drive".
3. Then click OK.
4. You should see a new item on the left which is your new Pool.
5. Click it and then click "Member" and then "Add."
6. Choose "Storage" from the drop down and then from the pop up select the drive from the drop down that you want to back up.
7. Then click OK.
8. Next go to Datacenter > Backup and "Add" a backup.
9. From here you can create a backup. Fill it out as you normally would.
10. Under "Selection Mode" you can click "Pool based" and from "Pool to back up" you can add the Pool you just created.

Hope this helps anyone looking to do back ups other than bulk back ups and VM back ups.
 
Sorry folks but this is not solved. I thought the backup was running but I was wrong. So, just to be clear, if you create a "Pool" and add a storage drive to it (Type: directory) and then create a "Backup Job" (to save that storage drive to a much larger storage drive; Type: NFS ) and add that pool as the "Pool to backup" (so it's the only member of the pool) it will not back up. I was unable to backup my smaller "directory" drive to my large "NFS" drive. Anyone got any ideas how to do this?
