Block Level Incremental Backup with Netbackup 188.8.131.52 and vSphere 4
I have a question about enabling BLI (BLIB) on a NBU vmware Policy and was wondering if anyone can share any experience or tips.
I've been researching the benefits of performing a BLI (BLIB) backup on a virtual machine and it seems that enabling BLI (BLIB) backup will greatly reduce the amount of time that a full backup typically takes on a nightly basis and reduce amount of data backed up. However, are there any risks or penalities that you pay during the restore when using BLI (BLIB)? I've read through these articles:
but haven't read much on disadvantages to using BLI or restore penalities?
A little more background: We have a virtual machine that is a windows file server running windows 2008 (NTFS) with 1.8TB of used space. We have the opportunity now to perform a vmware snapshot backup however performing this size of backups 5x a week seems to be a lot of data to push thru not only the vmware backup host and media server but also to store on tape each night. BLI seems to be a good fit for this scenario however I want to ensure I understand the effects before placing it into production.
