<![CDATA[Backblaze encrypted backup with Rsync fails]]>Hi All, I am unable to complete backup of a nextcloud instance (~500gb) with backblaze. I know cloudron backup is not usually recommended for larger apps but I thought I'd give it a shot again now that more backup parameters are tweakable. The error I am seeing seems related to encrypted file name length, here it is below:

It seems like the length limit applies to path length not just the filename length

find . -type f -print|awk '{print length($0), $0}' | sort -n

Went into the web interface and deleted / renamed files longer than 156 bytes and finally cleared trashbin/versioned files

(wipes all deleted / old versions of files - careful):

sudo -u www-data php -f /app/code/occ versions:cleanup
sudo -u www-data php -f /app/code/occ trashbin:cleanup

@robi @girish agreed it would be awesome if there was an automated way to handle this in the future

I guess another (dangerous) idea is to simply skip such files.

If you run the command listed there, it will tell you what filenames are too long (run this using Web terminal):

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

this could also be checked by Cloudron and perhaps split into two objects/files.

This is a somewhat common side effect of encryption, unfortunately, when it comes to using object storage services. That's not even a BB issue specifically but common to many of those providers. In your case, you'll either need to determine what file is too lengthy to see if you can trim it down a bit so that it won't be too long once encrypted, or abandon encryption to any object storage services all together.
