I'm switching from a DLT backup system to a disk-based backup system with
occasional tapes for offsite backups. I followed the instructions at:
http://www.amanda.org/docs/howto-filedriver.html
Also have a look at the updated version:
http://wiki.zmanda.com/index.php/File_driver
and was able to get the first backup, but I seem confused about how to do
a "virtual tape" rotation. I never used a changer before, so perhaps I
don't get the distinction between the slot number and the tape number. I
basically want to have a 4 week level 0 rotation, where after the 4th
week, the first week gets overwritten, etc, just like a tape would.
I created a directory on a usb drive like this:
/mnt/usb/dumps
I put this in my amanda.conf:
dumpcycle 4 weeks # the number of days in the normal dump cycle
tapecycle 4 tapes # the number of tapes in rotation
tapetype HARD-DISK # what kind of tape it is (see tapetypes
labelstr "^FULL[0-9][0-9]*$" # label constraint regex: all tapes must
tpchanger "chg-disk"
changerfile "/usr/local/etc/amanda/weekly/changer.conf"
define tapetype HARD-DISK {
comment "Hard disk backup storage instead of tape"
length 300000 mbytes
}
> Then in my changer.conf, this:
For chg-disk, you don't need a changer.conf.
The number of "tapes" is taken from the dumpcycle paramater.
And the "changerfile" parameter is the prefix of a set of
files.
Also, chg-disk needs a "tapedev" which points to the root
of a directory tree, containing "slotN" (N = 1... up-to-tapecycle)
subdirectories.
Alternatively, you can use chg-multi instead of chg-disk, and
have a detail changer.conf containing the layout of your
vtapes.
There is an example in the wiki.
multieject 0
gravity 0
needeject 0
ejectdelay 0
firstslot 1
lastslot 2
you probably mean "lastslot 4"
slot 1 file:/mnt/usb/dumps/FULL0
slot 2 file:/mnt/usb/dumps/FULL1
slot 3 file:/mnt/usb/dumps/FULL2
slot 4 file:/mnt/usb/dumps/FULL3
