staged backup - File replication

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.
