Changing Tapes
2002-11-03 03:30:41
For some reason AMANDA doesn't ask me to put the second tape in.
Can anyone see any obvious problems??
(please note I'm only evaluating the product at the moment, so
some configuration setting may be weird)
some settings in amanda.conf
-----------------------
dumpcycle 0 days # the number of days in the normal dump cycle
runspercycle 2 # the number of amdump runs in dumpcycle days
tapecycle 4 tapes # the number of tapes in rotation
runtapes 2 # number of tapes to be used in a single run of amdump
tpchanger "chg-manual" # the tape-changer glue script
tapedev "/dev/nst0l" # the no-rewind tape device to be used
#rawtapedev "/dev/null" # the raw device to be used (ftape only)
changerfile "/var/lib/amanda/DailySet1/changer"
#changerfile "/var/lib/amanda/DailySet1/changer-status"
#changerfile "/etc/amanda/DailySet1/changer.conf"
#changerdev "/dev/null"
tapetype STD-5000 # what kind of tape it is (see tapetypes
below)
labelstr "^Daily[0-9][0-9]*$" # label constraint regex: all tapes must match
infofile "/var/lib/amanda/DailySet1/curinfo" # database filename
logdir "/var/lib/amanda/DailySet1" # log directory
indexdir "/var/lib/amanda/DailySet1/index" # index directory
define tapetype STD-5000 {
comment "Sony STD-5000 DDS2"
length 1500 mbytes
filemark 183 kbytes # from tapetype util
# filemark 48 kbytes #
speed 237 kbytes # from tapetype util
}
define dumptype always-full {
global
comment "Full dump of this filesystem always"
compress none
priority high
dumpcycle 0
holdingdisk no
index yes
program "GNUTAR"
comprate 0.5,0.5
exclude "*core*"
}
-------------------------------
I decreased the capacity of the tape on purpose so I can force it to use the
second tape.
I had to create the "/var/lib/amanda/DailySet1/changer" file manually since
the system was complaining that it couldn't find the file. It is only an
empty file.
The disklist file
-----------------------------
localhost /etc always-full 0
localhost /home always-full 0
localhost /squid always-full 0
#localhost /usr always-full 0
localhost /var always-full 0
aris /usr/local always-full 0
aris /var always-full 0
aris /home always-full 0
localhost /usr always-full 0

AMANDA's report
-----------------------------------
These dumps were to tape Daily01.
The next 2 tapes Amanda expects to used are: a new tape, a new tape.

------------------------------------
For some reason instead of asking for a second tape so it backs up
localhost:/usr, it delays the operation and it looks like it does an
incremental backup.
I'm not using a holddisk.
