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?

 

[Hannes Laimer]

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).

oh i seee, thanks for your information

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.

Hi at all,
I want to backup my VMs from Proxmox Host to a Synology NAS.
Active Backup for Business only supports VMware and Hyper-V at the moment.
Now I am searching for another way to backup my VMs.
With the Active Backup for Business Agent?
Or with Veeam Agent?
Or is there another way?
Regards Arthur

The recommended way is Proxmox Backup Server. Either running on the same Proxmox or on a separate Machine.

Create an NFS share in Synology, mount it to Proxmox using the gui and just set your backups to use the NFS drive. Go to Datacenter -> Storage -> Add -> NFS and fill in your applicable details

@louie1961 OK, that sounds simple.
Then I don't need a Proxmox Backup Server?

Correct, PBS comes in handy if you need to manage the backups for more than a couple servers.

No you absolutely do not need PBS. There is more than one way to skin a cat, as they say.

Actually this isn't correct either. PBS is useful if you need deduplication, which NFS can't provide or if you want to back up the actual Proxmox host and not just the VMs and CTs. But you can back up as many servers as you want with NFS. NFS, like PBS, is only limited by the capability of your infrastructure.
