USB Disk as backup

[jensie]

Dear community,

I'm a newbie to Proxmox and I love the environment so far. Hence I wanted to setup a backup to an external disk. I followed the following tutorial https://www.youtube.com/watch?v=lZjMxdBPH7M

Steps followed :

1. Formatting to ext 4
2. Create director in /mnt called /mnt/usb-drive
3. Finding the uuid with ls -l /dev/disk/by-uuid/*
4. Adding to /etc/fstab the following /dev/disk/by-uuid/31010205-a0ed-4e74-ac98-a68f66bcd06e /mnt/usb-drive ext4 defaults 0
5. Using mount -a to mount the disk
6. In UI : Datacenter - storage - add Directory

Questions :

1. How can I revert back without "breaking" anything ?
2. Would it be possible to add a part of the number of TBs to a VM as a secondary drive (store video, image files) ?

Thank you so much,
Jens

hi,

How can I revert back without "breaking" anything ?

what do you want to revert?

Would it be possible to add a part of the number of TBs to a VM as a secondary drive (store video, image files) ?

yes, you can passthrough the partition to the VM (but you won't be able to migrate the VM to another node with this setup)

something like this should work:

qm set VMID -scsi1 /dev/yourdisk

scsi1 can be changed according to your vm config (can be seen with qm config VMID)

@oguz Thank you for your quick reply. Based on what you wrote, it doesn't look like something I want to keep the storage capacity as I defined it. What would be the procedure to get ride of what I've done ?

still not sure what you want to revert but you can pretty much follow the steps backwards:

1. remove the directory storage from the UI
2. umount /mnt/usb-drive
3. remove the line from /etc/fstab

and you should be back to step 1 with an ext4 formatted usb
