Will do, James. I have not been able to recreate the held lock issue. I was starting/stopping jobs a fair bit at one point, and can't... be precise about where in the backup cycle those cancellations happened that a cleanup might not have happened. I will watch for it in the future. When I said there was no RAM pressure, I meant that was true for the server. However, my jobs all had 1GB of RAM. Your suggestion clued me in; because that value must be set after you setup the backup job, I had never noticed it before... or, not realized how critical it might be. I have bumped them all to 6GB of RAM, and so far, I've been seeing backup successes. Barring the question below, I'd say we could close this issue. The lesson learned is that I need to provide my backup tasks more RAM. Because I have some RAM to spare, I'm going aggressive, and giving things 6GB. I did not attempt to settle on a smaller amount, for anyone who comes along after--- I just gave the tasks a limit that I considered to be "a lot" in this context. I still see some things like the errors below. The backup completes successfully, but I'm unclear why there would be errors like these sprinkled throughout the backup. Is the relative path full/snapshot/app_... actually correct? Or, should that be a full path (e.g. the base path I provided at setup time along with the relative path)? In the command that succeeds, it is a full path.

yes- was my error/ all resolved. Issue was I had disabaled some of the app backups under app level but then had selected to back these up in global settings but seems the global settings do not overide the app level backup settings/ nor is there anything in global settings to inform backups for sepcific apps have been turned off at app level (maybe this could be added).

@simon said in Since v8.2.3: "Backup failed: Too many executable files.": As an idea: wouldn't it perhaps make sense to check this independently of the backups? Yeah, I think it's possible. Right now, we haven't focused on it because we have to then give feedback to the user in different ways when multiple apps fails but some succeed etc.

@joseph oh geez, ok thx ️

Ah this is good information and indeed a likely a problem for rsync backups with a lot of files (not sure how the rate-limit turns out in the end though)

thanks, fixed in https://git.cloudron.io/cloudron/box/-/commit/1d1a7af48ebd41fa9a54f73c124a708c226e38e8

Found https://rsync.samba.narkive.com/DFt4GEa9/over-stdin-stdout which has some interesting discussion.

@eddowding said in What's the fastest backup and restore method?: I have 175GB and it takes about 12h I guess something is very wrong. Yeah, my backup of about 350GB takes about 2 hours (from a Hetzner Dedicated Server in Finland Helsinki (HEL1) to a Heztner Storage Box in Falkenstein (FSN1)) IMHO your issue is very likely due to those "too good to be true" iDrive offer pricing they had which I guess you went for.

@girish Thanks, that works.

@msbt I also forgot about that option actually, such a long time ago when I wrote all that code

For restic, can you upvote here - https://forum.cloudron.io/topic/1575/backup-improvements-restic-backend ? It should be possible to add a new restic backend like tgz/rsync. Though, we still have to figure out how we can "support" it. But that's a separate topic.

@girish my initial questions are all resolved now. I'm having some new problems though. Namely that it seems the Cloudron installer is installing Gnome which is making my server enter sleep mode. I disabled it now but I'm confused as to why Gnome is being installed.

@girish Sounds good, thanks.

@robi The fsmetadata.json is only used in rsync backups. It's used to keep track of empty directories and 'x' bit of files when using rsync mode. We do this because object storage services (like s3, gcs and friends) cannot track this since they are not a filesystem but an object store. This is not needed in tgz because tgz format can encode this information inside the tarball. In essence, fsmetadata.json is usually owned by root. If it's owned by yellowtent, it's probably because maybe you restored the Cloudron in the past or something. The restore logic changes the permission of all files to yellowtent after downloading so that restore can continue as non-root user.

@girish Ah okay, that makes sense on the tgz part. Unfortunately I haven't had much success at all in any quicker times (in fact it's often closer to double the time than tgz, taking between 1-2 hours) when using rsync in my tests for OVH Object Storage. But maybe I just haven't found that 'sweet spot' yet. I'll keep testing. Thanks Girish.
