"Backup Failed" since the last Cloudron Update

[nebulon]

This AWS node module was updated at https://git.cloudron.io/cloudron/box/-/commit/b5fad74ea08e4c6cd06edf881612223549fb4eb3#fa288d1472d29beccb489a676f68739ad365fc47_14_14 so maybe that introduced the incompatibility with exoscale

So to be on the same page, your other Cloudron where backups are working, is on an older Cloudron version?

[girish]

I tested this with a test exoscale bucket in de-fra-1 region and it works. I wonder if this is IAM/Role related. I just gave it wholesale all permissions to objectstorage. Maybe you have something more specific?

[potemkin_ai]

@nebulon thanks.

Both boxes are 8.0.4. Both back up to Exoscale.
The only difference I can see is that the one that works points to https://sos-ch-gva-2.exo.io, and the other (that doesn't) - to https://sos-at-vie-1.exo.io.

I wouldn't expect the endpoints to be somehow different, as it would complicate operations for Exoscale, but that is really the only difference I can see.

[girish]

Test bucket in sos-at-vie-1.exo.io works as well . I am only testing with small backups if that matters. Does the small backup fail for you ? Like a single app? Maybe it's some multi-part stuff which is failing

[potemkin_ai]

@girish I tried single app backup and it produced a completely different error:

Sep 03 14:09:48 box:tasks update 4918: {"percent":30,"message":"Retrying (6) copy of ../../2024-08-06-010000-624/app_ps.domain_name_v1.17.0.tar.gz.enc. Error: IdenticalCopy: Source and copy are identical (contents and metadata). 400"}
Sep 03 14:10:08 box:tasks update 4918: {"percent":30,"message":"Retrying (7) copy of ../../2024-08-06-010000-624/app_domain_name_v4.88.3.tar.gz.enc. Error: IdenticalCopy: Source and copy are identical (contents and metadata). 400"}

It is also interesting to note, that I clicked backup on a single app and it's backing up all apps (that is just a snippet).

And - yeah - the error is different, so I guess we have a few of bunch of issues here.

[girish]

I see. I can't reproduce this on Exoscale SOS. Anyone else here use Exoscale?

Also, do you hit issues with other providers too or just Exoscale?

[potemkin_ai]

I gave up with S3 - never liked a connected to it IAM, after all, tried to switch to Hetzner's storage box - it doesn't work as well, here are the logs:

The ssh command in question, when executed directly from the command line fails indeed with error message: exec request failed on channel 0

I've tried to allocate more memory to the backup process - just in case - but it didn't help.

Switching to rsync didn't produce any good results either - it's extremely slow and the logs are full with errors creating directory and files upload is just stalled.
SSHFS connection appears green, reconnection doesn't help.

@potemkin_ai said in "Backup Failed" since the last Cloudron Update:

Can you try port 23 of Hetzner? I haven't seen this error before though.

[girish]

I can confirm that even for me port 22 fails with that cryptic error. Port 23 works.

[potemkin_ai]

@girish , thanks - the port was the thing to blame here, thanks!

One more question, if you don't mind: I can see that sub-accounts are not recommended to use with SSHFS - is still actual with Cloudron v8, or it's a relic of the past?

[girish]

@potemkin_ai We haven't tested with subaccounts in a while. If it works, you can use it. There is nothing really on Cloudron side wrt subaccounts. The docs are only having the information since we last tested it.

[potemkin_ai]

@girish yeah, I understand there is nothing about Cloudron here - just wanted to check your experience / understanding here. Thanks for sharing!
