OST vs CIFS for BackupExec 2012
I am running BackupExec 2012 and recently bought 2 x Dell DR4000 as my backup media appliance. I am planning on having one DR4000 locally and one at a remote location for replication. While setting up the DR4000, I've learned that the DR4000 can not replicate to each other if OST containers are used. However, it will replicate to each other if I use CIFS containers.
The delima comes in when setting up the jobs for backup.
1. Using OST, I can setup the backups to target the local DR4000#1 then "Duplicate" to the remote DR4000#2 and Tapes Library at the same times. The Duplicaiton is being controlled by the Symantec BackupExect server.
2. Using CIFS, I can usetup the backups to target the local DR4000#1 then "Replicate" the conntainer to the remote DR4000#2 and to Tapes Library. The Replicaiton is being done by the DR4000's and run indedpendently from the Symantec BackupExect server.
*** Sorry, no picture for this one but it's a just a straight backup job to the DR4000#1 then Duplication to Tapes Library.
Which one would be the prefer method? Let the BackupExec server do the Duplication? Or let the DR4000's do the Replication? Is there Pro's and Con's to teach methods?
