After backup: Destination is read-only?
I'm working on implementing a proper backup procedure as most experts on this forum recommend. But when trying to backup a large amount of data, I keep getting this error message: Backup: Error bac...
Have been looking for a solution for this problem for a long time, but never managed to find the root cause.
In the end, I decided to remove the offending subdirectory that contained a file backup of a Windows system. This solved the problem with the backup procedure.
Have narrowed it down to my "Documents" share that is causing the problem. All the other shares backup without issues. Will try to narrow it down further in the coming period.
If I connect the disk to the PC and look for files and dirs with read-only attribute set, it finds nothing. Strange. The NAS just told me there is a read-only problem.
If I check for dirty bit, it tells me the disk is clean.
If I do a check disk on the drive, it tells me that no problems were found.

We've been having these issues since the original OS6 and it's only on NAS drives were the USB drive is unplugged after backing up.
We have a numbe rof customers who rotate between two or more USB backups and even when you select 'Eject after backup' every few weeks this problem occurs.
Customers with only one drive that is permenantly connected have never had this issue, so it's a bug in the software or hardware.
In most cases, if you mount the drive in a PC and let the OS "repair" it, the drive becomes readable again.
Usually what is happening is that the dirty bit is being set on the drive.
