Howdy,
I'm using Slackware GNU/Linux 12.0 and would like to back up certain
files in my home directory: these are just data and configuration files,
not system files of any kind. Reading the `tar' manual I came across
the backup scripts, on my system in /usr/bin/backup. I created a
backup-specs file, and have gotten a bunch of errors that don't seem to
jive with the documentation. Here's my backup-specs file:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
# backups for joel
#
ADMINISTRATOR=joel
#BLOCKING=8
TAPE_FILE=/dev/sdb1
VOLNO_FILE=/home/joel/var/backup/volno_file/
BACKUP_HOUR="now"
# BACKUP_DIRS="
# /home/joel/ado
# /home/joel/data
# /home/joel/docs
# /home/joel/svn_repo
# /home/joel/Mail
# /home/joel/News
# /home/joel/lisp"
BACKUP_FILES="
/home/joel/office-directory
/home/joel/.emacs
/home/joel/.emacs-custom.el"
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
The directories are commented out for testing purposes (to avoid doing
the whole thing).
When I run backup I get:
/home/joel/etc/backup Super-User > backup -f --time=now
backup -f --time=now
/dev/sdb1: Invalid argument
Backing up -f at Thu Nov 29 12:22:28 EST 2007
tar: -f: Cannot chdir: No such file or directory
tar: Error is not recoverable: exiting now
/dev/sdb1: Invalid argument
sleeping 60 seconds
C-c C-c
/home/joel/etc/backup Super-User >
Observations and questions:
1. are the options are being accepted as arguments?
2. whatever I put for TAPE_FILE I get invalid argument, except when I
get "invalid ioctl for device" --- does this only work with actual tapes?
3. everything I find on the internet is about how to clone a system,
backup system files or a bunch of other stuff that would be useless
to me: does anyone use /usr/bin/backup? It sounds like it's designed
for the purpose I want, so I'd really like it to work.
Thanks for any help you can offer,
Joel
