Hi.
I have been using Amanda for years in a variety of places.
In the case below I am looking after a small school, so the budget is
minimal and I am using a lot of second hand stuff, in this case
4/8BG Sony's, HP's and so on.
The amanda server backs up itself plus that bastion host.
I use two tape drives in the server, one for the OS related stuff
and one for the user data including the samba stuff.
I have never come up with this problem:
FAILURE AND STRANGE DUMP SUMMARY:
lalalalala /samba lev 1 FAILED [dump larger than tape, 10101550 KB,
skipping incremental]
It is true that 10101550 KB is bigger than the tape size, this is a 4/8GB
Sony SDT-5000 which I have given the following setup:
# MMS TAPE 0 @ ADMINSERVER
define tapetype SONY_SDT-5000 {
comment "Internal SONY SDT-5000"
length 6000 mbytes
filemark 100 kbytes
speed 500 kps
}
I turned the hardware compression on for the tape drives via the jumper setting
on the drive
and I do not use softwware compression.
I know I should not use hardware compression cause amanda likes to "know".
However, since I have a small tape drive only, I decided to use a fairly
generous amount in the compression ratio ( I only told it that it has 6GB)
and it is less CPU intesive to use HW compression.
amtapetype in both drives tells me that HW compression IS enabled.
Executing "mt status" yields:
[root@lalalalala /home/amanda/etc/DailySet1] #>mt -f /dev/amandatape1
status
SCSI 2 tape drive:
File number=0, block number=0, partition=0.
Tape block size 512 bytes. Density code 0x13 (DDS (61000 bpi)).
Soft error count since last status=0
General status bits on (41010000):

So what am I not seeing here?
