Full, consistant app backups?

Hi all

I’m a new TrueNAS User and I plan to run some Apps like Immich, Nextcloud, Paperless-ngx and some other.

Now the most important question for me is, how I can do consistant backups of my apps to be able to restore them fully?

Can you help me guys ?

Thank you and regards
Lukas

There’s several methods (at least). Here’s two.

Some apps, not familiar with all of yours, have backup software or can easily be scripted to have a full consistent back. In Nextcloud case, the Nextcloud manual tells you how to do a consistent backup. So, in my case, I back it up from within the container via a shell script. In other apps like Emby, the software comes with backup software. I just use it.

Another way that is easier is to (likely script again) shut down all apps, take backup, start them up. Or an app at a time if you wish. Pretty much guaranteed good consistent backup.

I’m sure there are other ways as well. Off the top of my head.

This sounds good for me. How I can setup / run scripts for backups as you described ?

But there is no easy way to backup my apps via TrueNAS Web GUI ?

Many Thanks!

Personally having a lot of service running i rely most on replication of volumes. Also (but not so often) i copy folders and files via SMB to an external disks (2 click with free file sync).
Managing stacks with Portainer i have also all YAML into his native backup + a private GitHub repository

I do it exactly this way.

ok sounds more advanced. I just want to have an easy / good way how I can backup my (docker) apps with all needed data.

Replication will not give consistent backups depending on how you set things up. Nextcloud for example has a very specific sequence to get a consistent backup, and, if you don’t have all pieces in one stack, they may depend on each other. But it is ok in most cases.
