Backup hangs

[ekevu123]

Hi, I am importing a Nextcloud app backup in Cloudron and it repeats this message in the logs for quite some time already:

Dec 15 20:45:36 box:tasks update 473: {"percent":75,"message":"Downloading 2368M@0MBps"}

with just the time changing.

Is it normal that the percentage is not moving at all?

I restarted the backup but I get the same error, the speed drops to zero in the process.

Please share the following information:

• Cloudron Version
• Backup Configuration

Cloudron Version 7.3.4

About the format: tgz

It can store file names with up to 256 characters, provided that the file name can be split at directory separator in two parts, first of them being at most 155 bytes long.

So with bug folder structures this can lead to errors.
You might want to try using rsync instead of tar if that is the case.

[ekevu123]

@BrutalBirdie But wouldn't that only apply to future backups? Or can I try to reinstate this backup this way?

[BrutalBirdie]

@ekevu123
The question is, is this even necessary, do you have this large folder structures in your Nextcloud?

Also since you are on backblaze, be sure your backup timing do not overlap with their Scheduled Maintenance Window.

[ekevu123]

There can be a few large file names, but not many.

Thank you for pointing out the maintenance window, I didn't know that. But that is not yet, so it shouldn't have any impact.

I am wondering if I just see what will happen until tomorrow morning (maybe it will continue at some point) or if it makes sense to use rsync, but I am not sure if that works if I made the original backup in another format.

I tried it already several times and get stuck at different times.

[BrutalBirdie]

@ekevu123 you can also just cancel the currently running backup and just click backup now, so sort of restarting the backup.

[ekevu123]

@BrutalBirdie I cannot do a new backup, I need to implement this first as the original cloudron installation broke. I tried to restart the import already several times.

My only other alternative is to reupload everything from my computer.

Maybe you can try a few variations of https://docs.cloudron.io/backups/#concurrency-settings to see if this helps? Hard to say why the connection speed slowly drops to 0, but I have seen this in the past as well.

[ekevu123]

@nebulon I only have the memory limit and the upload part size as options, nothing more when using tgz.

[nebulon]

@ekevu123 right, then try a few variations of those.

[ekevu123]

@nebulon It worked when I set both to maximum, many thanks!
