As it was said by others, RAID 0 may not be the right choice. Virtual
tapes and tapespaning allows Amanda to extend a backup across several
physical disks, so you don't need RAID 0.

Amanda backup every DLE into a single file, except you specify
tape_splitsize. This could be usefull, if your

In fact compression depends on your data, do you know how much they
compress?
Full/incr depends on your data, how your disks ar

Ok, I'm hijacking a thread. Sorry about that. But, really, it does fit in.

Sure you want to do a backup to a Raid0? When one disk crash, you ll loos the
data.
Here I use a Raid6 Array out of 15 320 GB Sata2 disks + 1 hotspare. So 4 disks
can fail until i lose data.
Having a recoverable backup is the most important thing

Yes I do understand that and I didnt mention the number of backup servers.
Is it a recommendation of 1.5TB (raid-0 750x2) to backup the maximum
of 10 to 12 hosts? or will that be too much of a backup server to do
all the 10-12 hosts at once (including incremental and full)?
Should it be recommend

In RAID0 750GB x 2 = 1,5TB
But still that isn't enough.

My mistake, you have 1.5 TG of backup space.

Hi all,
I just wanted to share my experience.
I'm usually using hardware compression on my backup server (because all
data to be backuped ,1.2TB, are local) to save it some CPU. As a result my
backup were going quite fast (about 4 hours) but the load balancing was
far from my expectation (back
> Just taking into consideration of compression effect?
In fact compression depends on your data, do you know how much they
compress?
Full/incr depends on your data, how your disks are full, how much data
you need to do incr every day?
Try to use the reverse approach: what data you cannot afford

First time you add and dump a DLE, update should fail because there is
not yet such info file.

Hello!
I'm running a single-server configuration of Amanda 2.5.1p2 on FreeBSD 6.2.
Recently I added a new DLE. The next amdump run this DLE got dumped, but
this message was in the report:
driver: FATAL infofile update failed (hostname.com,'newDLE')
