Sebastian,

Could you elaborate on the usage of SMTAPE to disk?  

For my purposes, a staggered weekly or event monthly backup to some other media is my only requirement.  Fulls are fine, as is storage rehydration (though it would be very beneficial if I could keep it in deduplicated fashion as it would allow me to have backups more often \ keep them longer).  

What would be ideal is if I could use dump\smtape (as a scheduled job, perhaps) to copy the filesystem to a remote NFS share (say, on a commodity NAS device).  

>From further reading, it appears that "remote ndmp" can be used to stream the NDMP dump directly to my backup media server (e.g. Backup Exec), which I could configure to write either to a tape device connected directly to the backup exec server, or to disk storage (e.g. iscsi connection to aforementioned commodity NAS device).  

I've found evidence that with "priv set diag" one can use smtape to copy a volume to another volume on the netapp and copy it off, though I don't see any real benefit to doing so other than the space savings.  

Any other creative ideas?  I could use an NFS client and a copy job from the .snapshot directories, but that seems troublesome to maintain and monitor.  

Steve, after thinking about the Amazon AWS (and I presume Glacier?) comment you had I'm interested in hearing more.  Have you heard how this is configured?  In the past other clients have needed to initiate either a direct connect with Amazon or an IPsec tunnel off of routers announcing address space via BGP.  I'm assuming this isn't required for lower bandwidth implementations?  

Thanks,
Mike

Hi James,

just to mention:
since SV/SM is based upon SnapShots that are by design *readonly*, it's not possible to 'wipe' them through file system means. But if a hacker actually gains access to the destination filer itself and messes with it (e.g. vol destroy)...

And yes, you can SMTape. (Neat thing: it keeps dedupe savings, as opposed to NDMP-based backup)
smtape
NAME
na_smtape - image-based backup and restore

smtape backup [ options] path tape_device
smtape restore [ options] path tape_device
smtape restore -g path
smtape restore -h tape_device
smtape abort job_id
smtape continue job_id [ tape_device]
smtape status [ -l ] [ [ -p path] | [ job_id] ]
smtape help [ subcommand ]
DESCRIPTION
The smtape command is used to manage backup and restore operations. It allows user to backup a
volume to tape, restore to a volume from tape, abort or continue an operation, show the status of an

Thanks everyone for your insight.  A VTL isn't in the budget at this
point, and candidly I'm not totally sold on the combination
snapmirror\snapvault with a pair of filers
geographically separated being insufficient, but the client has a
particular need.

I'm pretty happy with SV to a geographically diverse filer, but on
another mailing list I'm on there's some discussion about how any online
backup could be wiped by hackers. I have no interest in setting up a
tape infrastructure, so what options are there for offline disk backup?
Can you SMTape to disk? NDMP perhaps?

Thanks,
