I got a great new QNAP (253A), where I have all my Data now and wanted to backup them to my old one (119II+) per "NAS to NAS" Replication. But after it the Backup was Finished, I hat an Error, that some Files in the Source have Vanished!
Luckily I have another Backup so I can restore this files (over 600 are missing!), but thats very shocking. I would understand that some files could not have been copied, but deleting Data from the Source should never happen!
It seems that it has Problems with some Filenames that include Unicode Characters like ÄÖ, etc. These were neither locked, nor temporary Files (mixture of Pictures, Books and Videos).
Does anyone know how this has occured and how to prevent it?
Specifications:
NAS to NAS over local Network (will be external as soon as the backup works)
activated Options (roughly translated from German): Only copy different Files; remove additional Files on Remote Target; be efficient with spread Files
Size: ~3-4TB

It seems that I cannot delete the Threat... Please consider it done!
There must be something wrong with either the Harddisk or the QNap itself because there are missing Files, some Directories cannot be deleted,,.. but this (should) have nothing to do with the backup-job itself.

Re: NAS to NAS .. vanished source Files
so I guess the 2 bay unit is not running on raid1 then ?
otherwise a single disk failure would not have those effects

Re: NAS to NAS .. vanished source Files
So, I have managed to solve my Problem...
As mentioned, the Backup was not the Problem, it only showed that one existed. When I switched the Harddisk from my old QNAP to the new one, something must have happend with the HD-Index.
The bad Block Check and both the short and long SMART Checks showed that the HD was fine and did not fix anything. But when I unmounted the Drive and used an f2chk on it, it found (and fixed) numerous errors and now it run perfectly fine and has no errors on the second check.

Re: NAS to NAS .. vanished source Files
maybe think of starting over with your drives .. moving the drives over will have them in legacy mode ... missing out on features (snapshots, etc)
