Hi All,

I have some question about backup functionality of NetApp (FAS270). We
have TSM server connected to Adic s10k library (2xlto2) and some stg
pool on external storage. All via FC, but we don't use netfree for
backup.

So, my question is - what is preferred method of backup NetApp? We can
use NDMP, but I heard:
. NDMP sucks (it's file-serving oriented, so backup they CAN do, but
poor than make that native b/a client)
. NDMP probably need strange connection to library (one man from
NetApp told us that FC build in them MUST be connected directly onto
library, another man from TSM support that must be connect to SAN).
Which is true?
. NDMP isn't stable.  We want to backup/archive business data, they
MUST be readable in any time we hold this on TSM - some people, on
that list too, isn't sure about that.
. What about restoring ONE file from backup? Is it possible? Whiteout
restoring full NAS?
. Is it any other solution for backup NAS? Critical for us is backup
acl for files/directories on NAS - we have heterogeneous network, we
(plan to) connect to NAS from AIX, Linux (redhat and debian, but NFS,
different version) and Windows.Any machine can write, any read, so
it's very urgent to always have ACL.
. single point of failure for NDMP via FC.
. more?

If anyone have experience in that, please write.
