SUN StorEDGE L400 2 tape, 8mm drives
I've searched for items on tape libraries like the L400 and similar, but haven't come up with good results. I'd really like to try Amanda, but Im getting frustrated and feeling a bit stupid. It seems rather difficult to find easy installation notes for my situation. I have an SUN StorEDGE L400 Autoloader (SCSI) with 10 slots and two tape drives. It uses Exabyte 8mm, 170m tapes. I'll be running the backup software on Solaris 8. Are there any newbie friendly notes to help set up Amanda to work with this type or similar type of tape library. I can't be the only one who has one of these things. What driver is best to use for controlling this kind of drive? mtx Does anyone have a similar tape library configuration file they could share?? I hate that this library is sitting here unused. Thanks for any help offered. Julie
Q: simple but how ?
Hi! I've installed in my debian the amanda system. Thank's to amcheck it seems my
config is ok, but I've some doubts and questions (it's no clear for me).
1) My tape is a PowerVault (the server is a dell poweredge 4400) and I make use of
dds4 tapes ( 40gb ). I've typed the following descriptors in my amanda.conf:
define tapetype DDS-4-20{
comment DDS-4 PowerVault without compression
length 2 mbytes
filemark 65 kbytes
speed 1255 kps
}
define tapetype DDS-4-40{
comment DDS-4 PowerVault with compression
DDS-4-20
length 4 mbytes
}
Then my tapetype var is: tapetype DDS-4-40
Do I suppose this will work properly? Have anyone experience with DDS-4 tapes and
amanda?
2) I still haven't the tapes (quantity) , but I must demonstrate to my boss that
amanda works and will work. Then, I've only 2 tapes dds4 and I thinked the following:
- doing a full backup every week (on friday night) ( simple ;-) ).
I've labeled the tapes ( tape01, tape02) and I would like to configure my amanda.conf
to this way. (the first week amanda demands to me tape01 .. the next week tape02 ...
01 ... 02 .. )
I've tried to configure my amanda.conf but I'm not sure it's ok. I've the following:
dumpcycle 0
runspercycle 2
tapecycle 2 tapes
runtapes 1
tapetype DDS-4-40
... etc
and my crontab.amanda runs amdump every friday night.
Is this ok? I must to change anything?
Best regards,

Re: downgrading
Well, I ran 2.4.4b1 for a few cycles. The results are mixed. On some runs, I can read all the tapes fine, including file marker 1. On other runs I get the same problems with the same messages in the logs. I've put the cleaning tape in and still no go... robin On Thu, 20 Feb 2003, Joshua Baker-LePain wrote: Would 2.4.4p1 actually help?

Thanks for any help offered. I believe you have two options. View the device as two separate devices each with dedicated slots (say 1-5 and 6-10) then run two separate amanda configs and amdumps. With this option you have to be sure that each amanda config accesses different client hosts if the amdumps are to run concurrently. The other possibility is to use the RAIT ?driver? to stripe a backup across the two drives. Then the library will look like a 5 slot changer with a double capacity and speed drive. jl -- Jon H.

Re: Q: simple but how ?
Hi!
define tapetype DDS-4-40{
comment DDS-4 PowerVault with compression
DDS-4-20
length 4 mbytes
}
This length number is probably too optimistic. This assumes that your
data compresses with a 2:1 ratio, which is rarely seen in real life.
FWIW, here's my tapetype with DDS4 drive using hardware compression:
define tapetype DDS4 {
comment DDS4 using hardware compression
length 25000 Mbytes
filemark 0 Kbytes
speed 2816 Kbytes
}
The length number is really just a guess (I think I underestimate the
compression a little, but since I only have 10 GB of data this is not
an issue for me right now). The speed number is taken from avg tp
write rate as reported by Amanda's nightly run.

Backup and recovery CD
A number of commercial backup vendors ship bootable CDs with a copy of their backup application installed. You can use these CDs to restore a system that was totally toasted, due to massive disk failure, being hacked, etc. I'm wondering if anyone has ever developed something similar for AMANDA. I'm envisioning something like the Red Hat installer, which boots up, lets you drop into a limited shell and lets you partition disks. The AMANDA bootable CD would boot up, let you format disks and give you a limited shell, and then let you run amrestore by connecting to the tape drive (or whatever archival media you are using) of your remote backup server. Just curious if anyone has ever gone down this road and if so, how far did you get? Thanks, Kevin -- Kevin M. Myer Systems Administrator Lancaster-Lebanon Intermediate Unit 13 (717) 560-6140
Help getting tape changer to work on Solaris 2.8

Re: Backup and recovery CD
For restoring linux based systems, I imagine that almost everything is already there on the KNOPPIX CD (http://www.knopper.net/knoppix/). You could boot from that (it would probably recognize some but not all hardware, test with your own), then you could compile and install amanda (with the correct configure options) and reconnect over the network to the backup copies of your indices. steven On Tue, 25 Feb 2003, Kevin M.

You can use these CDs to restore a system that was totally toasted, due to massive disk failure, being hacked, etc. I'm wondering if anyone has ever developed something similar for AMANDA. One of my colleagues has built a bootable rescue CD based on the Knoppix Gnu/Linux distribution (see www.knoppix.net if you don't know Knoppix). His CD includes an amanda client besides our usual tools and goodies. I have just recently used this CD to clone two of our machines, testing the disaster recovery in case of a complate hard disk failure. Steps are: - booting from the rescue CD - setting up networking and starting sshd to be able to work comfortably from my workstation ;-) - partitioning the hard disk, setting up swap, creating file systems - mounting the root partition somewhere like /mnt/target - recovering the root partition using amrecover via the network - mounting the remaining partitions into the recovered root partition's mount points - recovering the remaining partitions - setting up tmp on the target partition (since /tmp is normally excluded from our backups), giving it the correct permissions - chrooting into /mnt/target and making the system bootable (quite easy with grub) - rebooting and testing the system. Works great if the new machine is identical to the old one. In my case, I ran into a (small) problem because the clone machines were only Pentium I while the original machine's kernel was built for Pentium II and higher. However, since Knoppix (and thus my colleagues's rescue CD) are based on Debian, apt-get install-ing an appropriate kernel wasn't very hard :-) The most tedious part of this procedure was changing the tapes (only a single DLT drive here). I should really take a look at the file: driver some time...
