Backup to NAS Synology

[simrsta]

hi everyone
I want to ask the best way to backup to a Synology Nas

Is there a way to back up to a Synology Nas but only back up the latest data, not back up from the beginning?

because backing up data from the start takes a long time

and why sometimes the latest data from new backups is smaller than the previous day

No, what you want is deduplication, so the same date is not saved again, but reused from older backups. For that you can take a look at PBS[1]. But with a NAS alone what you are describing won't be possible.

We've been running PBS at work inside an VM running on an DS1821+ pretty fine. The Storage inside PBS is just an NFS Share from the same DSM.

What do you mean, PBS is installed on the Synology Nas?
How to do?

thnks for information
can pbs install in proxmox ve in another server?

PBS can run in a VM, the NAS is mounted on the PBS instance and used as a datastore, PBS does all the deduplication and integrates with PVE. The NAS is only the storage, nothing more.

Some more performant (and expensive) Synology NAS allow you to create VMs using the Package Synology Virtual Machine Manager

Though possible, but depending on your workload it could give a noticeable performance hit which is why we migrated our PBS from our Proxmox Cluster to a separate machine (DSM).

Alternative for backups (if you’re hosting Windows VMs) is using Active Backup for Business and install the agent on your VMs. With ABB you have control over retention and also the option for single file restore.
