I have a few databases which is quite large sizes from 1TB to 4TB. Currently it's taking more than a day to complete a full backup. I did not turn on compression & dedupe from commvault level as I'm using Dell's EMC Data Domain as my main storage for backups, thus all my backups goes through hardware compression & dedupe. This setup was done many years ago and has remain so till now.
I was wondering, is this setup the correct method? I do not have any clue why it's being setup this way as the previous engineers has long left the company.
Does using hardware compression really helps a lot compare to Commvault level compression & dedupe? I'm really concern as by using hardware compression, the media agent will be transfering a full chuck of 1TB or 4TB through the network into the DD for compression & dedupe.
Anyone has a setup similiar to mine & what is the best practise for this scenario? The databases I'm refering to is both SQL & Oracle which are all running on a physical nodes not VM.
