Hi,
We have a new 5230 appliance where the internal disk has been set up (by default) in the following way:
Catalog 20% - around 930GB
Advanced Disk 16%
De-duplication Pool 64%
We intend to backup to site A, then use AIR to replicate to site B (another 5230 appliance) where the backup will be eventually vaulted off to tape. However, some data will stay at site A until its expiry date (1 year). We have various retention times and clients.
1. Are there any calculations for the amount of catalog ratio to backups. Is 20% catalog to high, should I resize this. I know its an open question somewhat but is there any rule of thumb?
2. As you can see, I have a mixture of Advanced Disk and De-dupe disk. How do we balance between de-dupe space and advanced disk? What is the difference? We want to get the benefit of de-dupe for every backup so why wouldnt we configure the whole capacity to be De-dupe disk and have no advanced? Would I use Advanced Disk for some backups and De-dupe for others?
So we would end up with:
Catalog 20% - around 930GB
De-duplication Pool 80%
Could someone help explain my options?
Kind Regards
