Hey all,
Can anybody tell me how to exclude an ibay from a tape backup. I have an ibay directory full of music that takes up too much room an does not need backing up
regularly. It fills my tape so I just want to exclude that one directory from backing up.
-
Looking at /etc/e-smith/templates/etc/flexbackup.conf/10Exclude_expr00, you might be able to exclude an ibay using (note the tiny dot at the end of the third line):
mkdir -p /etc/e-smith/templates-custom/etc/flexbackup.conf
cd /etc/e-smith/templates-custom/etc/flexbackup.conf
cp /etc/e-smith/templates/etc/flexbackup.conf/10Exclude_expr00 .
pico -w 10Exclude_expr00
and add $exclude_expr[2] = 'ibays/<ibayname>'; to the bottom of the file. Save your changes, run expand-template /etc/flexbackup.conf
(You might want to test this before playing with the templates by simply adding the $exclude_expr[2]... line to /etc/flexbackup.conf and running a backup... Just be sure to template it before you forget or the changes will disappear at some point when you're not expecting it...)
-
Thanks for your reply. I did a trial like you suggested and it failed. Here is a copy of the log. Could you help me further. The directory I excluded is home/e-smith/files/ibays/music . Any help would be appreciated.

That needs to be /home/e-smith/files/ibays/music you are missing the first /
or you could try config setprop flexbackup Prune /home/e-smith/files/ibays/music followed by expand-template /etc/flexbackup.conf Then look at your flexbackup.conf file and you should see your new setting in the Prune section.

config setprop flexbackup Prune...
Yes, that looks much easier than my "solution"...
It also looks like you may be able to specify multiple folders to "prune" by separating them with a comma?

man flexbackup.conf implies that if you wanted to use "exclude" you would need to use this in /etc/flexbackup.conf:
$exclude_expr[2] ='.*/ibays/music/.*';
Another suggestion from the flexbackup FAQ (http://www.edwinh.org/flexbackup/faq.html) is to test your proposed exclude or prune expression (for the '/' filesystem) using:cd /; find . -regex "<expression>"
I *think* but can't prove that the difference between 'exclude' and 'prune' is that you want your exclude expression to match every file name to be excluded, but that your prune expression should match a folder name whose entire contents are to be excluded. So, using the test expression above, your choices would be:
mkdir -p /etc/e-smith/templates-custom/etc/flexbackup.conf
cd /etc/e-smith/templates-custom/etc/flexbackup.conf
cp /etc/e-smith/templates/etc/flexbackup.conf/10Exclude_expr00 .
echo "\$exclude_expr[2] = '.*/ibays/music/.*';" >> 10Exclude_expr00
expand-template /etc/flexbackup.conf(note: the backslash before $exclude_expr[2] allows shell redirection as shown here. If you edit the custom 10Exclude_expr00 file manually it should not be included!)
or
config setprop flexbackup Prune '.*/ibays/music'
expand-template /etc/flexbackup.conf
And lastly - since flexbackup is filesystem specific, your music will be automatically excluded if you put it on another file system (like a USB drive) and mount that file system in /home/e-smith/files/ibays/music...
