<![CDATA[Backup using rsync encrypted gives "ENAMETOOLONG" error.]]>Hello,

It seems when using encryption and rsync for backing up Cloudron (this particular configuration is new to my environment), I get an error message with "ENAMETOOLONG", suggesting the file path or name of the file is too long.

The exact error in my case is as follows:

ENAMETOOLONG: name too long, open '/cloudron-backups/snapshot/app_6b96bd5a-0f84-43aa-8558-7544ec25b19e/36gHI-IuCvvayKXxGPRB1Q/ounM2diChi8DjI1Q3dzMDQ/gGJEz0QgDgsR3jo4XlgYXA/lqAVjQcV8mH8VRRpjjOr1g/kJEwyjEtwqB7Sx2f6L-GUw/fu1zv6VH8LxelOLxe0ub0bgswf82VC21bSpaTxbYSq8fHBlOMRamME-qppekZ+OAzSVbZVxrDKhuYkwdDOLWxWGnFX3QZMFdo0l1mjw54vs-piviwM4PIThP9VIlXwl8ngYif83b3MCNO5lyxmQedqOPbjeVBsJOCzttwAqHl04ys1iTlQIrQMY1d2+adF15nNzZONfL4l-Y8S6TnwAySPkhvBLZY8khSMjI6KcZ-8SO8y1ML-NIM3uyj3MtKVsW

How can this type of event be worked around / resolved? In other words, since the filenames are encrypted too I'm not sure which file this references so I don't think I can even try to work around it by editing the file name before it's encrypted. And if it only too long because of it's encrypted value, versus if it wasn't encrypted? If so, I wonder if the encryption can be improved to avoid lengthy file names?

This of course works fine with encrypted tgz method, just not encrypted rsync.

Any help would be appreciated.

I have opened https://git.cloudron.io/cloudron/box/issues/670 to track this encrypted bug. Let's see if there is a bug in the non-encrypted one in the other thread.

That's a shame, as that will easily add a lot of time to the time it takes to complete a backup, plus the extra disk space. 😞

Please see the caveat in https://cloudron.io/documentation/backups/#rsync-format (the last one). I will make it a warning so that it stands out a bit more. It's possible to fix but it requires some work.

It works fine with encrypted tgz. And if I use non-encrypted rsync, I actually get a different issue all together where it fails to remove a directory for some reason (I may make a different post about that because I'd ultimately preferred to use rsync since I have a large amount of data, and my understanding is rsync backups would be much quicker after the initial one, but please correct me if I'm wrong).

Edit: Created new post for the non-encrypted rsync issue: Backup issue in rsync non-encrypted filesystem type. Never moves past status of removing directory for one particular app (Rainloop).
