the number of copies is twice that. We exclude substantial parts of the

Hi Skylar, Allan,
Skylar - would I be right in thinking that you have 130 million files on your
Isilon or did you mean you have 130 million files across all versions? May I
also ask how many directories and user accounts are involved?

Our current state (in implementation now) is:

We only backup via NFS (we have no ACLs so CIFS would be an unnecessary
and huge performance hit). Here's what we've done:
1. Partitioned our data such that we can have a large number of
filespaces that we backup separately (in hindsight, we might have wanted

Allen,
Thanks for your response.
I did not include your option 0, because I was thinking "large file servers".
Your point about option 0 being potentially more viable if metadata is kept on
SSD is interesting. Does anyone have any first-hand experience with this that
they can share?

Isilon is great usable storage that you can scale in any direction. It
lives under the one Namespace and super easy to admin.

Re: [ADSM-L] Isilon
If you are going to use a filer, EMC doesn't support backups of its NAS devices
(that I have run into) except via NDMP dump.
Netapp on the other hand (or IBM-branded N-series, which is still a Netapp)
supports the -snapdiff api.
I just helped a customer convert about 40 hours worth of NDMP dumps

It is just NDMP, but you need to get the "backup accelerator" to do that.

for what it's worth, NDMP works with TSM, but that's it. NDMP is not the most
advanced backup solution and the TSM implementation is not the most feature
rich. I'd look into other solutions first before reverting to NDMP.
