Pull vs Push Sync

[spetrillo]

Hello all,

I have one PBS, that is backing up one local and one remore PVE. What is the concept of pull and push sync, and which one should I use?

Thanks,
Steve

This is answered in the manual:
https://pbs.proxmox.com/docs/managing-remotes.html

Historically PBS only supported pull syncs, push was introduced in the current version.

Personally I prefer pull sync Jobs, since they allow to put the remote PBS behind a Firewall, so in case a hacker or ransomware attack on my local Infrastructure the offender can't do anything on my offsite backups. For the same reasons I setup the permissions that the remote backups can pull from my local PBS but not edit or remive anything local and vice versa like recommended in the manuals chapter on ransomware protection:

I am sorry...I am definitely not getting it. My backup data resides on my PBS. I have one PBS. I am not pulling or pushing anything...I think.

Have you read the first link? It says:

A remote refers to a separate Proxmox Backup Server installation and a user on that installation, from which you can sync datastores to a local datastore with a Sync Job. You can configure remotes in the web interface

So pull and push sync jobs are for syncing backups between PBS servers which is useful for offsite backup and ransomware protection

Correct.

None at all, because pull or push sync is for / regards, as was already explained, synchronizing multiple PBSs. But you have only one PBS (with multiple PVEs).
