Difference in storage usage, zfs or ext4

[p-user]

I was wondering, is there any benefit from using the storage op de pbs as zfs instead of the (more lightweight) ext4?

FYI, I'm using the pbs on a VM on a Synology NAS, separate from my Proxmox environment. Since that NAS is not a heavyweight (DS718+) I'm wondering if there is any benefit from using zfs instead of ext4, I'm using it for standard backup/restore. The zfs uses one disk, so no raid advantage.

Thanks in advance,
Albert

Hi,
apart from the additional error detection by checksums and other nice features of zfs (e.g. zfs send/recv), you will not have an advantage by setting up the PBS datastores on ZFS over ext4 for such a storage layout.

Note that setting up verify jobs [0] is strongly recommended, especially on storage's without redundancy, in order to early detect possible data corruption of chunks.

Thanks Chris for the quick reply and explanation.
The Proxmox Backup Server is a learning curve for me, I just started using it.
I've set up a verify job, as you suggested.

Kind regards,
