Re: [Networker] NetApp NDMP backup session benchmarks

Done last week, 49 GB backup in 40 minutes, recovery in 60 minutes.
F825C to 2xLTO on LVD. Two backups concurrent, one 2-way, one 3-way.
However, I must admit that the data is a bit suspicious, I would expect a
slightly lower throughput if I had been able to load to complete 120GB test
data but the only DLT drive failed after the first tape of three.

Bye

Fellow Members,

We are looking at upgrading our backup environment having added a couple of
NetApps F880 filers with +/-10TB of data recently.  We already have a SAN
storage island, so are looking at SAN attaching a STK L700E jukebox (housing
either LTO drives or possibly 9940B drives), and linking the NetApp filers
to the SAN also, thus allowing us to associate drives with Filers as needed.
Initially, we then expect to use Legato to control NDMP sessions to enable
the dump of the NetApp volumes to tape.

My question is whether their are other Networkers who have similar
conceptual solutions who can give an idea of the read/write throughputs we
could expect for a single NDMP session, and what limitations/drawbacks there
are when using NDMP.

Any experiences welcomed,

Best regards,

Paul Broughton
