Guest gjb Posted February 5, 2008 Posted February 5, 2008 Hi, I am looking for some advice/pointers for replacing our current HSM backup regime based on legato diskextender. Currently we have sans or attached storage arrays (approx 4TB-6TB) attached to a W2K3 cluster. The files get moved to near-line UDO WORM in a Plasmon jukebox via diskextender. We aim to replace this with a new backup/archive paradigm consisting of a second RAID/NAS for initial file moves and then to backup the NAS to tape library for off-line archive/storage. This way we 2 raid copies "on-line" and an off-line backup. The problem I am facing is the best way to perform the file moves from the live RAID to the backup NAS.(on a limited budget and using something a little more sophisticated than basic batch file copies) I could use a backup tool e.g Bexec but I would like the NAS to have a copy/mirror of the actual directory/file structures. Double-take or similar synching software is not an option in the short term. Would DFS replication be a viable option or are there other solutions that someone could recommend? Any help would be greatly appreciated. Regards, GJ.
