Yes, it is possible, even likely, that the archive somehow got corrupted 
while rsynced.

Never run compare, I'm afraid. Looking in the mail logs for this list I 
did have problems with som files when I started using boxbackup. Can't 
remember if it got resolved.

I think the controller HW got messed up, the two disks that it handles 
got corrupted.

No.

Yes, by running bbstoreaccounts check fix.

I don't have a log right now, but in short.

In phase 2, check diectories... a couple of hundred "File ID xxx has 
different container ID, probably moved".

In phase 4, fix unattached objects "Recretating missing directory bfd9" 
amd the followed by thousands(?) of "Object xyz is unattached".

After phase 5 and 6 finish without problems, I get "3225 errors found".

The same thig repeats if I remove the bfd9 file from the archive and run 
bbstoreaccounst again.

I hope this helps, or i can send yu more information later today.

That soime of the fiels went missing I can live with, but I want to get 
as much as possible. During my operationms, the size of the archive has 
   gone from 211 GB down to about 130 GB, is that bbstoreaccounts check 
fix work?
