VMware Restore Process
I just put myself in a really bad spot. It's fine, I have a way out but I am interested in the methodology on how DP does VMware based restores.
So I have a 1.4 TB file server and it's incremental backups are roughly .1 TB a day. I have a ton of nearline storage so doing a .1 TB backup a day is really easy to do. My staging space for restores is 2TB (storage size limit for an NTFS volume). So while backup wise, I can support a ton of incrementals restore wise, I can only support 6 days. It appears like Data Protector stages all of the incrementals together, then does some magic, and then *poof* a vmdk appears that is the same size as the original file. In this case my vmdk is 1.4 TB. The problem with this is that I had a bad full backup one day and I am attempting to do a restore. The incremental is actually 10 days out which means the space I need is actually 2.5 TB to do the restore and of course this fails.
Can anyone answer me as to why DP cannot merge a single destaged incremental at a time? This seems like a massive caveat to the software. So while my phyiscal storage space can easily support backing up incrementals for like 30 days.
