Can you find out with which version this error started occuring? Maybe I fixed it already.
To further narrow down what did not work I’d have to know when that
file was last downloaded, and what happend after that. For example a
client timeout or server shutdown. May be difficult to find out if you
don’t have debug logs.
You can get rid of this error for this client by running a full file backup.
I’m pretty sure it was 1.4.1 beta 1 but not 100% sure on that.
I found the entry in urbackup.log on the server
014-07-09 00:36:22: ERROR: Could not remove file “/mnt/backups//140708-2340/Share/Accounting/Quickbooks/.QBW” in ::deleteFilesInSnapshot

I think btrfs logs in the kernel log if remember correctly, looks like kernel.log doesn’t go back far enough unfortunately.
So after a server reboot I’m getting this on other clients. I assume this is the same thing? This is with 1.4.1RC1 on the server. There’s no 140805-0236 directory on the server. I didn’t see anything useful regarding btrfs in the kernel logs.
04.08.14 23:40 Could not remove file “/mnt/backups/****/140805-0236/Exchange/priv1.edb” in ::deleteFilesInSnapshot - No such file or directory (errorcode=2). It was already deleted.

I think they gave me a hint. It may be fixed in the RC3 now (server side fix). If it still doesn’t work client/server debug logfiles would be nice.
FYI there may be other issues on that client that caused the assertions(crashes), because it probably deletes the shadow copy during the backup. This may be caused by not enough free space or a high write volume.
Still getting errors and urbackup on the server crashed again. These were the last lines in urbackup.log
