Arcserve UDP - Restoring from a NAS to the RPS server itself

Hello all,

We use Arcserve UDP 6 to backup our Branch Office servers to a local NAS connected via iSCSI, the Branch Office server is also an RPS server as we only have one server in the Branch Offices we are protecting with Arcserve.

We recently had to recover a complete server and the performance throughput doing a restore after a rebuild was dire, approx. 100MB per minute - would have taken around 7 days to restore 1.5TB.

Do any of you have any recommendations or experience with this type of setup, how do you manage this and what hardware do you use, e.g. local NAS, another RPS server etc?

Thanks, Andy

What causes the slow performance is your outbound internet/WAN speed and 100MB is really very good; but, ......
A NAS located at the site would be much faster; though, I would suggest it be a second backup device as the existing ones are offsite which is a good idea.

Hello Davis, thanks for the reply.

The NAS is on the same LAN as the server we were restoring to.  They are connected via GB NIC's and switching, the transfer speed was at 10oMB per minute over this connection.
We have resolved it though, and just in case anyone has the same problem the fix was to create a new Arcserve UDP datastore, and NOT enable de-dup.  It was the de-dup function which slowed performance down to a snails-pace as it had to uncompress, de-dup, and rehydrate the files on the fly - then copy them from the NAS to the server itself.
Not using de-dup has speeded to process up considerably, now 2.3GB per minute - hope this helps someone else in the future!
