Backup Central

Anyone backup an Isilon array? Using 3592 tape drives? The sales guys say it is just NDMP.
I am looking for just basic information (good, bad, Oh Smurf!). One may be in our future.

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.

It is just NDMP, but you need to get the "backup accelerator" to do that.
(It adds FC ports to the isilon and enables NDMP)

Here is the isilon guide for this.

I've just read about it, but haven't done it myself. I also read about
the IBM SONAS and that looks much more appealing from a TSM perspective.
(Built-in TSM client, uses its super-grid thing for the incremental scan,
hsm-like functionality)

We have a bunch of Isilon storage, and back it up using over NFS using
TSM proxy nodes. Our data is easy to segregate into virtual mountpoints,
though, which helps us get pretty good parallelism.

I took one look at NDMP and have stayed well away from it because it
simply doesn't scale. I have a feeling it's designed to benefit tape
library vendors.

We tested the backup accelerators a few years ago (about 2 ) and they
didn't fit our requirements. This was before they offered the Metadata
on SSD.

At that time they only supported a few tape drives for each accelerator
and the bottle neck was getting the data out of the cluster.

Because we don't backup everything in the isilon cluster and we had lots
of user facing Accelerator nodes we got better performance by running
multiple parallel TSM backup streams from one or two clients.

Again this is all based on the older isilon nodes and your milage may vary.

One thing I've mentioned to our Isilon sales rep several times is how
sweet it would be if we could run a real BA client on the cluster. Given
that OneFS on the backend is FreeBSD-based, it seems like this would at
least be doable for IBM. Now that EMC owns Isilon, though, I have small
hope of this ever happening.

We are looking at Isilon too, along with NetApp, BlueArc, and SoNAS. Backups are a real challenge as these get large in scale. Some observations:

1. NDMP requires periodic full backups. This generates a lot of backup traffic. If you're going over a long-haul network, this can be an issue. Note there are 3 versions of NDMP (or 4?). Some go direct to tape, some allow you to go to TSM. When purchasing a NAS with NDMP support, make sure you understand this if you're planning to use NDMP.

2. NetApp has snapdiff integration with TSM. Very nice. Avoids having to walk the filesystem, which is a big win. Restores can take a long time. That's an advantage of NDMP, I think. Backups are done from NAS clients.

3. SoNAS has integrated TSM client, which (I think) uses a journal in GPFS which again saves TSM from walking the filesystem each time. I'm pretty sure about this, but not positive. Also allows extension via TSM/HSM I believe. Nice on paper - no experience with it yet.

4. Isilon - has "backup accellerators". Yes, an integrated TSM client would be nice (to whoever suggested this), but what you'd really want is something to save TSM from walking the filesystem. I don't see this happening for the reason stated earlier - there's no partnership between EMC and IBM.

5. BlueArc - no experience or insight with this yet. I think you'd either use NDMP or a NAS client, similar to Isilon.

We're looking at all of these (and have a NetApp), so I'm keenly interested in others' experiences.

Hi Andy,
If you don't wanna run NDMP, I suggest that you maybe build a GPFS cluster and only used Isilon as dummy storage.
In that case can you build much larger filesystem then Isilon can do and you have much faster and better backup solutions.

I know that it could be waste of hardware and money but depend on how much data and retention period. But you will probably save money in the end if you going to have a lot of data and need to save it for more then 6+ month.

We're contemplating such a device, too.

In our plans so far, we're thinking 'replicate and snap' for DR
purposes. Longer term archives aren't currently under consideration,
but pleasantly they don't have the same frequency issues. If it takes
me a week to do an incr once a year, I'm less concerned.

This may be a bit off topic but consider this a thread bump....

We have about 25TB worth of unstructured data spread across seven windows servers using DFS. We are using TSM with a monthly image backup as well as daily journal based backups to collect the data but I'm concerned about restore times.

I have convinced managment that we need a filer but they do not want to purchase a file JUST to for file server backup/recovery. They now want to depoly test and dev VM's on the solution and possibly use the platform for virtual desktops (VDI) and maybe even a workstation backup solution.

I spoke with Gartner and without hesitation the recommended the ISILON over all other solutions. For those of you that already have ISILON do you feel it was the right choice?

We are an EMC storage shop so ISILON would be easy to sell but I feel better about purchasing a proven solutions (NETAPP) rather than something that EMC may chew up and significantly change.

My primary concern is still with the backup of the data contained on the device along with virus protection and access control. Please provide your feedback.

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 that normally took day,s to a single 2-hour -snapdiff TSM backup. And size is down from Terabytes a week to a few Gigabytes a day, because the -snapdiff API lets you do a true incremental of the stuff living on the filer. ( See the windows backup client manual for the requirements, they are very minimal - essentially just requires 7.3 or higher of Ontap, and that's been out for a long time. )

As far as what is good for VM's (and I'm speaking from a backup/recovery perspective, I'm not a VMWare expert): no 2 filer-type devices are the same. As long as you are talking really low utilization, almost anything will work.
If you are talking > TB of VM's, remember that for VM's we are back in the sad old world of needing to full dump all the .vmdks, usually every 1-2 weeks. So it's a matter have having the infrastructure IN the filer (drives, cache, paths) and the infrastructure TO the filer (fibre attachments or 10GigE between it and the TSM server) to get the throughput you need.

There was code around for a while, that compiled on Solaris, and could
understand NetApp's (essentialy) ufsdump format. With this you could read
an NDMP backup.

Skip foward a few years: Avamar's NDMP accelerator (a Linux box running
custom code) can take in an NDMP stream from a Celerra and output a
stream equivalent to a normal (Avamar) file-level backup client. That
product can do the same thing with NDMP backups from a NetApp filer.

I'm not advocating the product, or comparing it with Snapdiff, just
pointing out that at least one other product can do something novel with
the NDMP stream.

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

For backup/restore...
Isilon only provide NDMP or direct backup ala Cifs/NFS
# NDMP in TSM is only full and differential. there is no incremental
option. You need to purchase a "backup accelerator" for every 2 or so
drives you want to physically connect to the isilon cluster.
# Direct backup requires complete tree traversal but can be scaled. Uses
the same hardware that user's benefit from.

How these effect you depends on your data and backup windows etc
The newer Isilon nodes should be faster to do tree walks as their
Metadata is stored on SSD(Make sure you confirm this on the models you

I would still pick NetApp if you can. If your unstructured data is
large, snapdiff can save a lot of time.... essentially it can instantly
determine what files have changed since the last backup and only sends
the changed files through to TSM, eliminating any tree traversal.

PS ESXi using NFS is GREAT!!!

We have about 25TB worth of unstructured data spread across seven windows servers using DFS. We are using TSM with a monthly image backup as well as daily journal based backups to collect the data but I'm concerned about restore times.

I have convinced managment that we need a filer but they do not want to purchase a file JUST to for file server backup/recovery. They now want to depoly test and dev VM's on the solution and possibly use the platform for virtual desktops (VDI) and maybe even a workstation backup solution.

I spoke with Gartner and without hesitation the recommended the ISILON over all other solutions. For those of you that already have ISILON do you feel it was the right choice?

We are an EMC storage shop so ISILON would be easy to sell but I feel better about purchasing a proven solutions (NETAPP) rather than something that EMC may chew up and significantly change.

My primary concern is still with the backup of the data contained on the device along with virus protection and access control. Please provide your feedback.

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

For backup/restore...
Isilon only provide NDMP or direct backup ala Cifs/NFS
# NDMP in TSM is only full and differential. there is no incremental
option. You need to purchase a "backup accelerator" for every 2 or so
drives you want to physically connect to the isilon cluster.
# Direct backup requires complete tree traversal but can be scaled. Uses
the same hardware that user's benefit from.

How these effect you depends on your data and backup windows etc
The newer Isilon nodes should be faster to do tree walks as their
Metadata is stored on SSD(Make sure you confirm this on the models you
get).
