Hi,
Using Amanda on Solaris 10 "2.5.2p1,REV=2008.05.21" and amanda client on a
solaris 8 which I beleive has same version of Amanda.
I am not sure what settings for tapecycle dumpcycle should be used for
efficient usage of Vtapes. I'd like advise in setting those parameters in
amanda.conf
Here is the situation,
Data to be backed up is around 50G and grows by about 100-200MB each day.
I have 20 Vtapes and each tape is 4G size on the server. I do have total 300G
available on server disk but I just decided to start with 80G to start with.
Current settings in Amanda.conf are,
dumpcycle 7
runspercycle 7
tapecycle 20
dumpuser "amanda"
tpchanger "chg-disk" # a virtual tape changer
tapedev "file:/export/amanda/vtapes/test/slots"
changerfile "/opt/csw/etc/amanda/test/changerfile"
labelstr "TEST-.*"
#label_new_tapes "TEST-%%"
#autolabel "TEST-%%"
tapetype DVD_SIZED_DISK
logdir "/opt/csw/etc/amanda/test"
infofile "/opt/csw/etc/amanda/test/curinfo"
indexdir "/opt/csw/etc/amanda/test/index"
tapelist "/opt/csw/etc/amanda/test/tapelist"
#etimeout 600 # number of seconds per filesystem for estimates.
etimeout 3600 # number of seconds per filesystem for estimates.
#etimeout -600 # total number of seconds for estimates.
# a positive number will be multiplied by the number of filesystems on
# each host; a negative number will be taken as an absolute total time-out.
# The default is 5 minutes per filesystem.
#dtimeout 1800 # number of idle seconds before a dump is aborted.
dtimeout 3600 # number of idle seconds before a dump is aborted.
ctimeout 30 # maximum number of seconds that amcheck waits
# for each client host
holdingdisk hd1 {
directory "/random/amanda/amandahold/test"
}
define dumptype comp-tar {
program "GNUTAR"
compress fast
index yes
record yes # Important! avoid interfering with production runs
}
define tapetype DVD_SIZED_DISK {
filemark 4 KB
length 4482 MB
}
I'd like to retain backup for a month if that's possible by doing some
modifications in amanda.conf and adding more tapes of modifying tape size or
so..
Please advise..
Thanks
