Solved Error Copying Backup: InvalidObjectName: null

[JLX89]

Hello,
I seem to be having an issue where Nextcloud backups aren't working properly. As of the past few days everything seems to have been working fine, but since yesterday I started getting the following error:

box:backups [Nextcloud Domain] Unable to backup { BoxError: Error copying [DO Spaces Backup Name]:

Any help with this would be greatly appreciated!

Thank you!

@jlx89 what is your backup configuration like?

[JLX89]

@robi I'm hosting with OVH (US) and backing up to DigitalOcean Spaces (NY3).

[robi]

@jlx89 that doesn't answer my question.

Go to your backup settings and tell us what they are set to.

[JLX89]

@robi I'm using that setup, backups are setup to use rsync, schedule is set to everyday at 11pm, retention is setup for 1 week. Backups seem to be working for all apps, except Nextcloud.

[robi]

@jlx89 are they encrypted?

[JLX89]

@robi Yes, they are.

[robi]

@jlx89 take a look at these:
https://forum.cloudron.io/search?term=nextcloud backup encryption&in=titlesposts

try a manual backup
try turning off encryption

[JLX89]

@robi Yes, that seems to have been the problem -- I turned off encryption and it seems to have worked out. Even manual backups were failing, just changed it back and it failed again. This seems to have happened right around the upgrade to 6.1.1. I'll have to dig into the issue more. I really appreciate your help!

@jlx89 In rsync mode + encryption, there are filename length limitations - https://docs.cloudron.io/backups/#encryption . You can run the command below to see if you have large filenames (you have to run this in Nextcloud's web terminal):

cd /app/data
find . -type f -printf "%f\n" | awk '{ print length(), $0 | "sort -rn" }' | less

[JLX89]

@girish Thanks! This ended up being a combination of issues I believe. So throttling on the backups due to using rsync, encryption, and file names ended up being too long (only a few) So I've changed some settings around and it seems to have been resolved. I appreciate the help from both @robi and yourself.
