Hi Commvault experts,
We are designing an archiving workflow and we’d like to get your advice on the best practices.
Let’s assume the source is NetaApp with SnapLock volumes (WORM) and target LTO tape library with WORM media.
Our goal is to move/archive data from NetApp SnapLock volumes to WORM tapes for long-term retention (10+ years).
What is the ideal storage policy for this setup? Does it make sense to use a “staging disk” as a Primary Copy and then a DASH copy to the tapes, or is there a better workflow for WORM volumes (primary copy directly to tapes)?
We are also choosing between two tape strategies. The first is a "Clean Archive" where data is written only once to save media. The second is "Periodic Fulls" where we write the full archive again every so often for better safety. Given that the source data is immutable, which approach do you recommend?
Your input will be much appraciated.
