Ndmp how does it work

I probably wasn't that clear with my question. My question was based around the capacities I'm seeing on my volumes and the difference between them and what is actually written to tape. The used space within the volume is less than this, i. So why is the data written to tape more than the used space from within the volumes. This is handy when dealing with file servers with a lot files. Backing up the blocks gives you a huge performance increase.

The problem is with this type of backup the whole file system is backed up each time, so if its GB, and you've got 20GB worth of files, the backup would be GB each time. I think this is because from the netapp side each CIFS share or volume that you create is actually a file system by itself, you're backing up the whole file system RAW, and getting the increased backup size.

Did you mean:. ProLion RestoreManager creates a central, online file index of every NetApp snapshot, giving you a single catalogue-based view into your files. You can search snapshots using multiple criteria and restore files and folders right from within RestoreManager with a single click.

The catalogue is created by utilising the NetApp SnapDiff technology to efficiently identify changes between snapshots, whilst conserve the efficiencies of incremental backups.

NetApp users will be able to quickly restore to a granular level both from object storage in the Cloud and local backup targets. NAS vendors would then build integration that followed the NDMP standard Backup traffic is able to be offloaded to local or fibre channel-attached devices, addressing the bottlenecks from streaming data across slow networks Delivered the ability for centralised data management where […] February 9, Benefits of NDMP included. Is there a better way?
