I'm looking for some recomendations and guidance to improve my current Backup strategy.
Two locations connected via 1.5mbps MPLS link, each site holds approx 400gb of data that is backed up nightly using BackupExec 12.5 and an LTO3 tape drive at each location.
What we are looking to do is a simple cost effective way to replicate our data from our main site to our branch office and vice versa.
First thought was to use DFS replication. Only problem with that is if user at site A deletes files then they will be deleted at site b.
The data that will be replicated will be only for offsite storage / backup purposes so the users at the second site won't be accessing it.
Any thoughts on cost effective devices or appliances to do this for me? I've researched the HP lefthand and Dell Equalogics SAN's but the cost is quite high.
