We are currently running 7.5 on Windows and looking to add deduplication

The barcode and mediaID are entirely separate entities. Even though your

Use bplist. The syntax is a pain, but it works.

To be very honest, I have no idea what the detailed specs are behind
First of all, suck it Neil Conner. I'm about to disagree with Ed
(again) and there is nothing you and your fish eating friends can do
about it.
Gotten away with it? I'm not stealing bread from the supermarket, I've
made a calculated decision. I run 18 MD1000s in this configuration
globally
that are getting the same speeds when comparing
destaging speed to a back up taken directly to tape from the disk used
for staging ? Or do you just have to live with the performance hit when
destaging ?

Martin,
Even when we fully format the DSSU disk and we then run 1 backup job to this
disk and directly afterwards we duplicate it to tape we get
. In the
future, I'll consider your internet sensibilities before telling you to go to
hell.

Jonathan,
Actually we already tried out different sets of block sizes on the DSSU. 32
seems to be the fastest we can find. We do not use compression
Format your DSSUs with a 64k block size.
Use 64K block size on raid group.
Disable compression (if you can't use 64k block size.)
Lower the number of concurrent writes to the DSSU.
Occasionally clear the DSSU to relieve fragmentation.
Clear the DSSU, write a single backup to the disk, then stream
Have you checked the system log for NTFS corruption? I would run a
chkdsk /f S: just to be sure. Careful though, it will knock the drive
offline while the chkdsk is running.

What do your client list and backup selections look like? Why did you
select cross mount points, are you using NTFS mount points?
