Please excuse my ignorance, we're just about to buy a Filer or two but I don't have any hands-on experience yet.
We're looking at a first filer with about 2.5TB and my understanding is we could not do a tape backup overnight with only a single-drive tape subsystem. At this time, we would prefer not to invest in something like Legato to intelligently drive a multi-drive jukebox like the Spectralogic series, though this should be able to dump the full capacity overnight. ("enterprise backup" is down the road).
Instead, I was considering getting a second NetApp (probably refurb with transferable license) and backing up the first to the second. This seems surprisingly cost-effective. (I'd love to do SnapMirror but it's surprisingly cost-prohibitive.)-:
Is there a way to natively run dumps from one NetApp to another without Legato-ish middleware? without an intermediary client box doing NFS/CIFS mounts? (we need to preserve both filesystem attributes).
Is this a plain stooopid idea? Any better ones?
Again, I'm hoping to avoid jumping into something Legato-esque at this point -- and just do something cheap and reusable like another NetApp -- because we'll be looking into a more comprehensive backup solution later.
Thanks, and sorry for my ignorance. Pointers to docs welcomed.

Yup.
filer2> ndmpcopy usage: ndmpcopy [<options>] <source> <destination>
<source> and <destination> are of the form [<filer>:]<path> options: [-sa <username>:<password>] [-da <username>:<password>] source/destination filer authentication [-st { text | md5 }] [-dt { text | md5 }] source/destination filer authentication type default is md5 [-l { 0 | 1 | 2 }] incremental level default is 0 [-d] debug mode [-f] force flag, to copy system files [-h] display this message
Just enable your ndmpd (options ndmpd.enable on) and let it go.
Greetings,
Chris,
This is remarkably simple, as with most NetApp-related things ... just check out the ndmpcopy command in the filer documentation.
If you don't have your filer yet and don't have access to the NOW website, I'm sure someone here would post the relevant pages.
You could also Google for it, e.g.
http://ecserv1.uwaterloo.ca/netapp/man/man1/na_ndmpcopy.1.html

We too are just about buying filers. Our solution involves using NetApp's SnapVault s/w and the R100 Near-line storage. Yes, its definitely expensive than the ndmpcopy solution !
FAS9XX (Snapvault Primary) ---> R100 (SnapVault Secondary) - This takes care of our regular backups, as the R100 will have the Full backup and the nightly and weekly incremental as Snapshots. Hence there is no need to do a tape backup on a nightly or even weekly basis. We plan to do a monthly full of the R100 and send the tapes off-site just for DR purposes. (We already have Veritas Netbackup DataCenter edition and tape libraries).
We are also planning to use SnapVault for opensystems (Solaris and Windows) so that these non-netapp servers also can backup to the R100 thus almost eliminating all our nightly backups. This way we hope to cut down on time, effort and cost of managing tapes.
Hope many of you have seen this webcast from NetApp. Our solution is based on the Enhanced Backup (level 2) mentioned in this presentation.
