Best backup strategy for NextCloud?
-
The thing is and most people forgot with NC is depends on the user to put the files in the NC folder that gets created, if the user does not put the files into the sync folder nothing gets backed up.
I am saying this right ? or there is way to force backup ? like mapping the sync folder to C:\Users. But that is not what NC is made for ...
My theory is if you create NC folder for users in the desktop, and they dont use it = no backups.

What's your retention policy for data on NextCloud? I think that would help determine your backup method and software (along with RTO and RPO policies) and several other factors of course.
At what point in time should you be allowed to say "Sorry, our backups don't go back that far, so we can't recover that file from that period of time..."? As well as "The oldest copy I have is from XXX, and the most recent is from YYY.". It will take this long XXX to restore it, and cost this much XXX to restore it.".I don't have any of that
Essentially, VULTR's automatic backup only retains the latest 2 images. To me that's a little shallow. I'd like to push it to a week at least. For example if a virus or something screws up all our files late on Friday, I don't want to come in on Monday and find that our oldest backup is still screwed up. I haven't been able to find whether VULTR lets me download or transfer a backup on my own, then at least I could push that to another storage service.
Assuming I can't download an image, that leaves me having to do my own "standard" NextCloud backup procedure, grabbing my files and DB manually.
I'm ok setting this manual backup up, but I still am curious about doing it as an incremental backup just to save space. I'm just not sure how incremental will work with the rest of the NC files and database. Do I dump the DB and include it with each incremental backup? And if so, how does that help if I needed to restore a bunch of files from an incremental? I don't think that would work. Or maybe this situation would never happen?

BackBlaze B2 would be good. Or any other provider that you can script an rsync to. It sounds to me like you do not want backups. you just want a copy offsite.
If you want actual backups that is different. Then things like the script @black3dynamite mentioned or URBackup as @DustinB3403 mentioned become the best choice.We have a B2 account. That is really for archival storage but I guess that doesn't matter, I can still delete older backups without any issues in my account?

For us, NC is not for backups, it's for file sharing. We have different backup for workstations.
For that matter, I could cheat this whole thing and just backup the NC files daily as part of the normal workstation backup, but even those are one week incremental. At least it would be something, I'd have a week's worth of NC changes on a local workstation to pull files out of if ever needed.
Or likewise I could create a second backup on my workstation to do incrementals on NC only to our NAS.

To make it transparent, you can create a junction point instead. That way it makes backing up easier.

I'm left with these options then:
-
VULTR daily backup, only keeps 2. It can only be restored by recreating the entire node, no partial recovery.
-
A server script to send incremental backups of just the files off to B2 or wherever. These couldn't do full restores of the node, or NC itself.
-
A server script to do the "official" backup procedure of NC and send off to B2 or wherever. This might be the most flexible and normal solution, but I don't like having to keep so many copies of the entire file store if I can help it. It could be used to restore NC itself in the event the software is hacked or an update screws it up thoroughly (although this would not happen, as I take snapshots before those kinds of updates, I would restore the snapshot instead).
-
Use my local workstation to pull daily or 2x daily incremental file backups onto our local NAS. This could only be used to find accidentally-deleted files that are not in the NC trash bin but it couldn't restore the server, or NC software directly.
At the end of the day, it's all about the files. If I have to rebuild a VPS and install NC from scratch, so be it, as long as I have the most recent copy of files possible to upload back to it. The second concern is fastest turnaround for people to keep working and use the files. In fact, having the files backed up via a workstation to the NAS is probably the fastest way people can get back to work, because I can just shared the NAS folder internally as I fix everything.

Here's another backup option for file backups. It's called Restic.
https://restic.net/You can also backup to B2.
Here's the documentation too.

This can be forked into a new thread if need be - For larger amounts of data in NC how are you all handling the backups? I have a script that backs up NC (database, nc folder, and data drive) to a dedicated NAS. At some point the offsite replication to a remote NAS will take too long and never catch up on a slower WAN link. Is there a recommended way to do incrementals of the NC data? Using rsync? From all my research, it seems like everyone does it different and there is no "best practice". I don't see the need to copy the entire data set for each backup - especially when sending the backup job offsite.

Before backing up the database, nc folder and data drive, do you turn on maintenance mode first, backup and then turn it off after backup is complete?

@black3dynamite Yes. I also stop the httpd service even though it isn't necessary.

Am I correct in saying rclone would not be needed if you had an nfs mount on the local server where restic is installed?
-
@Obsolesce I have restic working without rclone and it is fast and simple. Have to try and script it now.

I used rclone in order to use OneDrive as a backup repository. It seemed like the easiest supported way to do it. How did you mount OneDrive without rclone? I'm sure there are more ways, just curious.
-
@Obsolesce Not using OneDrive. Using a NAS with a nfs share that is mounted via fstab.

Ah i see, yeah rclone was only used so I could specifically back up to OneDrive. Nothing more.

For me, I'm doing a mysqldump of the database, then using rclone to copy the files, the mysqldump, and the /var/www/html folder over to Wasabi.
