Hi all,

I was looking into storage usage of my Cloudron instance and I stumbled across some unusually high storage usage of my backups.. To clarify, my Cloudron server runs:

• a NextCloud instance with about 16GB worth of files (Cloudron says it's 40GB, but I guess there's some footprint for the installation and file versioning etc.)
• a Wordpress instance of a few MBs (Cloudron says 60MB)

Now, as far as I understand backups in rsync start with a snapshot and work incrementally from there. I do not upload/remove too many files from my server so the storage remains fairly constant. Therefore, I'd expect a backup size somewhere not too far above the 40GB.

I checked my backups and they were covering a quite whopping 66GB. Taking a closer look revealed some tar.gz files and my hunch is that they are remnants of my old backup setup into tarballs. My snapshot folder is filled as such:

• /app_<NextCloud-app-ID> (40GB)
• app_<NextCloud-app-ID>.tar.gz (20GB)
• /app_<WordPress-app-ID> (30MB)
• /box
• /box.tar.gz
• app_<unknown-app-ID>.tar.gz (I think this might be an old app I had)

So the tarballs are together over 20GB in size, confirming my hunch (because it would make my backups 46GB in size).

TLDR; Are tarballs saved in the backup/snapshot folder when backups are in rsync? Or can I remove tarballs in my backup/snapshot folder?

@jdaviescoates I use them for my own Cloudron instance! Works like a charm, they even have 18.04 with preinstalled Cloudron images so it was zero effort for setup I run my backups somewhere else though, so not sure about those.

Thanks for your reply @girish. I contacted customer support of Scaleway and they told me they do not throttle their object storages (which is what I backup to).

Scanning the log files, I found that it did in fact crash on a specific series of files. I think the root cause for this was that there was a single device of mine that halted on an auto-upload via the NextCloud app. I rarely use this device and did not notice it was stuck on an upload for days. I removed the files and ran another backup, this time it did not crash.

Is it possible that the backup script can timeout on such a partial/corrupted file?

@jdaviescoates My backups go via Scaleway. Was easy to setup because there was a Cloudron preset and guide for it, and it's free up to 75GBs AFAIK not green though..

@fbartels Indeed! I changed the title accordingly.
