Homelab #17 Set Up Backups for Proxmox

One of the three people who inspired me once said this

So the next problem we need to solve is Backup and Restore.

Reinitialize the disk

When I did YT dlp, I turned the disk into LVM storage (disk for VMs), so I have to format everything on this disk.

Shut down and detach the disk from the yt dlp LXC

vgdisplay #Xem tên VG (Volume Group)
lvdisplay #Xem tên LV (Logical Volume)

lvremove /dev/vg-hdd500/vm-112-disk-0 #Xoá LV
vgremove vg-hdd500  #Xoá VG
### Format lại
mkfs.ext4 /dev/sdd
mkdir /mnt/backup-hdd
mount /dev/sdd /mnt/backup-hdd
### Thêm vào fstab để auto-mount
echo "/dev/sdd /mnt/backup-hdd ext4 defaults 0 0" >> /etc/fstab

Configure backup in Proxmox

Back in the Proxmox UI, go to data center -> Storange

Click add and fill in like this

Scroll to backup and add

Choose the settings however you want.
