I have a ReadyNAS Duo (4.1.6) that has 2x500GB disks in. I have currently used 461GB and I am trying to do a full backup to an external USB drive (1TB).
I am having 2 problems.
(1) When I plug in the USB drive to the front USB port it does not detect the drive but instead tells me I have unplugged my UPS (which is connected to a rear USB port)!! I have to reboot the readynas in order for it to redetect the UPS and to pick up the USB drive!
(2)I have created a backup job with the following settings:
Backup: Volume c
Destination: Share 2 of USB drive
No Schedule (just want to run once manually)
Backup options: First time - Full backup, both checkboxes unticked.
The first time I ran the job the entire drive was one partition (NTFS) and it failed with this error:
Reason for failure:
Error encountered copying data from source path ==> /USB_HDD_1/NAS_Backup_141210 due to unsupported filename characters in the destination filesystem.
So I decided to parition my usb drive and created a 550GB ext3 parition thinking this might help.
That backup then failed again after copying about 19GB of 461GB. This time frontview told me 'the backup failed due to an unknown error' but there is no log for it. Only the previous log file remains.
