Hi all,
I am trying to create backup servers out of the following specs:
P4 3.0Ghz
1GB RAM
RAID0 - 750GB x 2 (SATA)
Hosts to backup: about 20 hosts with roughly 100GB each host.
What will be the complications and the limitations?
And also what are the recommendations?
Thank you.
Regards,
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')
The FAQ-o-Matic says that this is
driver: FATAL infofile update failed (hostname.com,'newDLE')
From top of my headf, I think it happens each time you add a DLE, but
shoul dnot happen later.
First time you add and dump a DLE, update should fail because there is
not yet such info file.

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
RAID0 - 750GB x 2 (SATA)
Hosts to backup: about 20 hosts with roughly 100GB each host.
So you have 20*100= 2TB to backup on 750GB
My mistake, you have 1.5 TG of backup space.
What will be the complications and the limitations?
Limitation is clear, you deon't have enough backup
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

In RAID0 750GB x 2 = 1,5TB
But still that isn't enough.
I would suggest you to buy something that could
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

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
In addition to doing everything to make sure a backup disk failure
does not destroy all your backups you need to take into consideration
the length of your cycle.
My experience so far has been with tape and I am just beginning in the
disk-to-disk with virtual tape. How long before Amanda

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

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

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.
