- Tabu - Quarter inch cartridge (QIC) tape backup utility.
- Copyright 1990 Roy C. Sigsbey - all rights reserved.
- This software may be publicly distributed at no charge.
-
- usage: tabu [-ddsk] [-sscsi] [-ttap] -b|c|l|r|x [name]
- -b = backup by blocks to tape
- -c = create backup to tape (name required)
- -d = dsk is scsi address for disk (default: 000)
- -l = list tape contents
- -r = restore by blocks from tape
- -s = scsi is scsi device name (default: HardFrame.device)
- -t = tap is scsi address for tape (default: 001)
- -x = extract from tape (name required)
- name = reference name (required for c or x)
-
- tabu.info ToolTypes may be set as follows:
-
- OPER=B backup
- OPER=C create (NAME required)
- OPER=L list
- OPER=R restore
- OPER=X extract (NAME required)
- NAME=name reference name (required for C or X)
-
- LIST=name list to file or printer
- SCSI=name scsi device name (default: HardFrame.device)
- DISK=nnn disk scsi address (default: 000)
- TAPE=nnn tape scsi address (default: 001)
-
- Tabu defaults to using HardFrame.device to access a SCSI bus. The SCSI
- address of 000 (as described in devices/scsidisk.h) is the default for
- the disk and the tape is defaulted to the address 001. Options -d, -s,
- and -t for command line; DISK, SCSI, and TAPE for tooltypes may be used
- to specify other configurations.
-
- Options b and r (Tooltype OPER = B and R) utilize a block by block
- transfer between devices. For the b (B) function, the disk is copied
- block by block until the last block on the disk has been read and written
- to tape. This is a disk image backup. For the r (R) function, the tape
- is copied block by block to disk until an end of file mark is encountered.
- This is a disk image restore. Both functions use a block size of 512
- bytes (industry standard size for both devices).
-
- Options c and x (Tooltype OPER = C and X) utilize AmigaDOS functions
- to access the disk. The name option (Tooltype NAME) is required for
- these options. For the c (C) option, the name (NAME) is the directory
- or disk or file to be backed up to tape. If the name is a disk, the
- subdirectories and files therein will be copied to tape and their names
- will be listed to stdout. If the name is a directory, it and all its
- contents will be backed up to tape and their names listed to stdout. If
- the name is a file, then only it will be backed up to tape and listed
- to stdout. Stdout may be redirected on the command line to any printer
- or file using AmigaDOS redirection. Stdout may be redirected in Tooltypes
- using the LIST option. Setting LIST=PRT: for instance will redirect the
- listing to a printer. For the x (X) option, the name must be a disk or
- directory. The contents of the tape are written to the disk or directory
- using AmigaDOS commands. The date/time, protect bits, and comments are
- also restored for the files and directories on the tape.
-
- The c (C) and x (X) options can be used to backup and restore any
- AmigaDOS file system (yes, including floppies). Although this seems a
- little like information that isn't real useful, it does give insight as
- to how these options access the disk.
-
- The two tape formats are not interchangeable. Attempting to restore
- with option r (R) from a tape created with option c (C) will result in
- a tabu error message indicating improper tape format. Attempting to
- restore with option x (X) from tape created with option b (B) will also
- result in a tabu error message.
-
- The last option l (Tooltype OPER = L) is used to list the contents of
- a tape created with option c (C) or to give the backup date for a tape
- created with option b (B). It lists the protect bits, date and time,
- size in bytes, and the heirarchical structure and names of the files
- and directories for option c (C) tapes.
-
- Note that a copy of tabu must exist on some floppy or other media than
- the disk being backed up. If for some reason that disk gets damaged
- (which is why we back them up) the tabu software won't be available to
- restore the disk data. A copy of tabu on the hard disk being backed up
- is OK and makes doing the backup easier. There is no copy protection of
- this software except by the user's trustworthiness.
