Re: [Veritas-bu] NDMP backups from Netapp using Netbackup
2010-07-27 11:37:43
We used to get HORRIBLE (8MB/s ish) performance doing CIFS backups of our NetApp filer, and I was pretty sure Symantec recommended against doing our backups that way (this was 3 years ago or so). We do backup exclusively to tape though so maybe that makes the difference.
Also I didn’t think NTFS permissions were restored correctly when using CIFs shares as your backup source.

With the new backup support for what was called pure disk the backup data is going to disk and only the changed blocks. But if I understand things the netapp would have to have code installed on it that would understand the pure disk api.
What Symantec is actually recommending now is to use a traditional Unix or Windows client and NFS-mount or CIFS-mount the data. Then do your normal backups to a PureDisk storage unit and do continuous incrementals and synthetic fulls. With the new PD code, a synthetic full only does pointer changes so they got like a bat out of...
As an extra bonus, because you're using a non-NDMP client, you can restore the file to anywhere, not just the same NDMP type of host that you started from. As a double-added bonus, a Unix or Windows license (list $2,595 to $6,095 for x86/x64 clients) is a LOT cheaper than an NDMP license, especially if you a have big filer (list $3,500 to $15,500).
The de-dupe option is VERY pricey though at $5k per front-end TB (MSRP). In our environment, we're about 180TB of used space at the moment. The list price of backup it all up with de-dupe would top a million bucks with the media servers and the de-dupe licenses. And that doesn't include the disk to put it to.
