First, thanks to everyone who commented on this thread. I really appreciate it. It looks like we are going to end up with replication because EMC decided to come in with a very good price on a second VNX for replication that is just a bit more than a large ZFS storage target. Hardware devices such as the Data Domain were ruled out due to cost and because our dataset and retention times only got 4 - 4.5x compression which meant that plain storage like ZFS was cheaper. We also ruled out continuous incremental backups like CommVault because they do it via either NFS or CIFS shares and only get either CIFS or NFS acls. This breaks when you are multi-protocol like us as the only way to get both CIFS and NFS acls is to run two backups (one via the CIFS share and one via the NFS share). cheers, ski _______________________________________________ Discuss mailing list [email protected] https://lists.lopsa.org/cgi-bin/mailman/listinfo/discuss This list provided by the League of Professional System Administrators http://lopsa.org/
