HOWTO

Create new backup repository

On PBS server:

Datastore->Add Datastore

New subdirectory will be created

Configuration->Access Control->User Management->Add

and

Configuration->Access Control->Permissions
Datastore->yournewstore->Permissions

to give the user access, Role is usually DatastoreBackup


On PBS guest:

Datacenter->Storage->Add->Proxmox backup server

For "Datastore" enter the name as used on the PBS. For fingerprint:

proxmox-backup-manager cert info | grep Fingerprint

Then:

Backup-Add storage: your-pbs

PBS API

Create cookie

PBS=your.pbs.server
curl --silent --insecure --data "username=zabbix@pbs&password=n0tmyp4ss" https://$PBS:8007/api2/json/access/ticket | jq --raw-output '.data.ticket' | sed 's/^/PBSAuthCookie=/' > cookie

Test cookie

curl -XGET --silent -k -b $(cat cookie ) https://$PBS:8007/api2/json/

Recovering files from backup

export PBS_REPOSITORY=mypbs:mydatastore
proxmox-backup-client snapshot list

Output like: vm/109/2022-01-25T20:18:02Z │ 200.00 GiB │ client.log drive-ide0.img index.json qemu-server.conf

# proxmox-backup-client map vm/109/2022-01-25T20:18:02Z drive-ide0.img

Image 'data2:vm/109/2022-01-25T20:18:02Z/drive-ide0.img' mapped on /dev/loop0
# lsblk

└─loop0p3    259:2    0 195.9G  1 part

 

mount /dev/loop0p3 /mnt/loop/

mount: /mnt/loop: cannot mount /dev/loop0p3 read-only.

mount -o loop,ro,norecovery /dev/loop0p3 /mnt/loop/

and that should be it. After you're done:

umount /mnt/loop
proxmox-backup-client unmap /dev/loop0

 

TBD: explain how t o use kpartx and friends to acces LVM volumes

 

FAQ

error pruning backups - check log (500)

Possibly a permissions thing, which is good. Leave pruning to the backup server

Pending removals
