Please help diagnose repo broken by syncing to onedrive

[nickchomey]

My backup repo is stored locally, but i sync it to Onedrive (this is far more performant than backing up to onedrive directly). But it is breaking lately. I assume the issue is with the syncing, not rustic, but i dont know how to investigate deeper to see which files are missing/corrupted, and why.

Can someone please give some guidance/suggestions?

Hi @nickchomey
It seems rustic cannot even open the repo. Can you check if there is a file /mnt/d/OneDrive/Rustic-Backups/popos/config and if what size it does have?

[aawsome]

(And yes, we should add more context here, but you could also use a higher log-leve like --log-level debug or --log-level trace which should give better information how far we get)

oh, very weird. i just ran rustic backup again and it worked. i have no idea what might have changed... I'll report back if i find anything else later

[aawsome]

Seems like the mount is somewhat "instable" and sometimes does not return files/data. At leas this is how it looks to me..

[aawsome]

But yes, I agree this seems like a OneDrive issue..

[nickchomey]

There's no "mount" - the repo is in the local filesystem (separate internal NVME drive)

I'm on linux now, which doesn't have an official client. I'm using Insync HQ, which mostly works great. I dont know why there would be issues at all, since the repo is local and then syncs remotely asynchronously. I wish i could just use rustic with a remote repo, but it is VASTLY slower like that.

I was mostly just hoping it might be possible to identify a particular file that was corrupted/missing, so that I could try to identify what went wrong with the syncing.

[kapitainsky]

I assume the issue is with the syncing,

I think your setup is over engineered. Syncthing does not support Onedrive. So you go through at least one extra hoop for no reason but mounting onedrive to your filesystem. Simplify syncing as much as possible. Less things to go wrong. Why not to use for example rclone to sync it directly?

[nickchomey]

Thanks for the input

[nickchomey]

I'm having trouble seeing how this is a syncing issue. Ive recreated the repo many times, and it always inevitably ends up breaking. Also, it only started happening recently.

Here's more logs

That worked to build. But when I run rustic backup i still get the same errors (though no filepaths shown.)

Hi @nickchomey this looks again like a index file with small or 0 size. Can you list the index files in you repo and look for empty files? Especially one of the (or the) latest ids in the traces should be small or empty.

[nickchomey]

Thanks, I found a 0B index file and deleted it. Still not sure where the issue is coming from (likely the syncing), but at least it's clear to me now what to look for. I'll update here if I find anything conclusive

[aawsome]

If index files are missing, you can run rustic repair index to re-create them.

[nickchomey]

I think the problem might have been that 2-way sync was sporadically downloading some empty index files, and probably was happening due to lots of changes in short period of time. I switched to only do 1-way sync from local to onedrive for the rustic repo - will wait to see if anything breaks again.

Its good to know about rustic repair index though - i'll try that if the issue comes back, and perhaps even build it into my bash script that runs via cron job - if there's an error, try to repair.
