-Amanda with floppy tape drives on Linux:
-(A.Gebhardt <albrecht.gebhardt@uni-klu.ac.at>)
-
-
-Amanda now supports the ftape driver version 3.04d (see
-http://www-math.math.rwth-aachen.de/~LBFM/claus/ftape).
-It adjusts the blocksize automatically to 32k and supports QIC volume tables.
-
-It uses only one open() call for writing backups to one tape, so the
-"busy"-lamp of the drive will be on all the time. (With normal amanda
-code it would be off in pauses between two files written to tape.)
-
-For volume table support you have to get libvtblc first (Available at
-ftp://pc02-stat.sci.uni-klu.ac.at/pub/Linux/libvtblc). This library contains
-the functions and subroutines from the vtblc utility, distributed with ftape.
-(May be, this library will be part of a future ftape package).
-
-You have to set the raw tape device for volume table operations, usually
-/dev/rawft0, either via "configure --with-ftape-rawdevice=..." or
-with "rawtapedev=..." in amanda.conf (configure checks for /dev/rawft[0-3],
-to get a guess for this value).
-Dont forget to make this device read/writeable for your backup user.
-
-For compilation you need the header files from ftape 3.04d in your include
-tree.
-
-The volumetable of a tape "amlabeled" TEST-VOL2 with 4 backups on it
-would look like (listed with vtblc utility from ftape):
-
-gamma@backup[backup]$ vtblc
- Nr Id Label Date Start End Space
---------------------------------------------------------------------------------
- 0 VTBL "TEST-VOL2 " 23:08:06 03/15/98 3 4 0.00%
- 1 VTBL "gamma //beta/C 0 " 00:00:00 03/15/98 5 374 0.68%
- 2 VTBL "gamma sda2 0 " 00:00:00 03/15/98 375 1029 1.21%
- 3 VTBL "alpha sda2 0 " 00:00:00 03/15/98 1030 1906 1.62%
- 4 VTBL "alpha sda6 0 " 00:00:00 03/15/98 1907 8092 11.45%
- 5 VTBL "AMANDA Tape End " 01:45:15 03/16/98 8093 8094 0.00%
-
-With lvtblc, currently available with the libvtblc library, you can list
-the complete label strings
-(44 characters, not only the first 22 characters as with vtblc):
-
-gamma@backup[backup]$ lvtblc -l
- Nr Id Label Date
---------------------------------------------------------------------------------
- 0 VTBL "TEST-VOL2 " 23:08:06 03/15/98
- 1 VTBL "gamma //beta/C 0 " 00:00:00 03/15/98
- 2 VTBL "gamma sda2 0 " 00:00:00 03/15/98
- 3 VTBL "alpha sda2 0 " 00:00:00 03/15/98
- 4 VTBL "alpha sda6 0 " 00:00:00 03/15/98
- 5 VTBL "AMANDA Tape End " 01:45:15 03/16/98
-
-Note on datestamps:
-volume 0 (amanda label): reflects the time of starting the backup
-volume i (backup files): amanda datestamps of the backup files
-last volume (end marker) : reflects the time of finishing the backup
-
-
-I tested this on a Linux machine (P90 / 96Mb RAM / 256 Mb swap) with two other
-clients (Linux / WfW) using
-
-kernel 2.0.33,
-ftape 3.04d,
-amanda 2.4.0b6p4
-
-with an internal Iomega Ditto 3200 (TR-3) drive attached to an Iomega Ditto
-Dash controller (at 2000 Kbps). My "tapetype" follows:
-
-define tapetype DITTO-TR3 {
- comment "Iomega DITTO 3200 Travan 3 tape drives"
- length 1500 mbytes #
- filemark 29 kbytes # ???
- speed 256 kbytes # = 2000 Kbit/s ?
-}
-
-Note on filemark size:
-Filemarks are not written to the tape (they are written to the header segment
-and use there 128 byte), so their size could even be 0. But a tape segment
-takes at least 29 kb (+3 kb ecc-code = 32 kb), so in the worst case an eof will
-waste 29 kb.
