Backup restore ct is very slow (zfs linstor Storage)

[jesusdleguiza]

I'm doing a backup restore on a ct that weighs 500gb, but only has 80gb occupied. When the backup is on the local disk it takes 3 and a half hours, but when it is on pbs it takes 7 hours. Because in both cases it takes a long time. Is there a way to reduce the time? They are on zfs with linstor. Regards

Are you using ssds or hdds? Due to the amount of small files in the data store it's expected that performance with hdd is suboptimal. You could use a special device on a SSD to speed it up. But this needs serious consideration and planning since in case of a loss of the special device you can't access your data anymore. More information can be found in the the manual: https://pbs.proxmox.com/docs/sysadmin.html#local-zfs-special-device
