I bought a Synology DS212J last week. I have 2 WD 2TB drives inside, in a Hybrid Raid setup. I first tried using Chronosync to scan the NAS and backup to a hard drive connected via USB to a Vantec dock on my Mac. After waiting over 3 hours for it to scan and compare the NAS drive to the USB connected drive to work out what new or modified items needed to be backed up, I gave up. It seemed to be scanning REALLY SLOWLY!!! I then tried connecting the Vantec dock directly to the NAS, formatted the drive to (ext4) and tried using Synology's Backup & Restore to backup the drive, but it kept giving me errors and wouldn't complete the initial backup. The only option I have left is to buy another DS212J and use the network backup function to keep the two NAS's in sync. The reason I don't want to use Time Machine is because i want to make a backup of my NAS at work and be able to take the backup home and work on the files at home. Does anybody have a suggestion. I'm a bit disappointed that it's not working as I had hoped it would.
