I did something similar with a backup script that copies only files that
change. However it does not take into account files that have been
deleted. You would then just need another simple script to run before
this one that would copy the backup directories to foldername-Tuesday
ect. If you use this you will need to make some minor changes to reflect
your environment. I have a bunch of other scripts that just call this
one. One for each machine I backup and one that is a batch of all the
machines I backup that I have sitting in cron.daily.
Example: scriptname someuser somepassword computername computershare
pathwithinshare locationofpst
The last variable is for backing up outlook pst files but it can be
omitted as well as the pathwithinshare if you are backing up the root of
the share.
Let me know if you come up with a way to have it remove deleted files.
I am also working on a better way to handle logging.
Let me know if this helps.
The script in case you care :)

Subject: Re: need method of backing up files
Well, there are so many ways of doing this that it's difficult to know
where to start!
There are two parts to what you want to do: scheduling when the backup
happens and doing the actual backup.
The scheduling is easy - use cron. man crontab will get you started on
that. One thing to be aware of is permissioning - if it's all on one
box, then root could run the backups fine, but you might not want to run
it as root, in which case a user like operator is used, but it runs the
actual backup binary SUID root.
Doing the backup:
A lot depends on how often you want to restore, and how you want to do
this - do you want to pull out individual files, or restore everything
in a give directory? How much data is there - is it necessary to
compress the backed up data?
If _ALL_ you want to do is copy files from one place to another once per
day, retaining permissions etc, then combine find with cpio. You can set
find to find only files which have been modified within the last day.
The commands you'd use (taking the first of the examples you give) would
be something like:
cd /home/peter
find . -depth -mtime -1 -print | cpio -pmudv /mnt/1monday/peter >
{Some_Log_File}
by using different options to cpio, you can also use this technique to
create a single archive file or go direct to a tape - say once per week
as a full backup. The man page for cpio should help you there.
If you want to simply create an archive of anything that changed since
the last backup, you could use dump. This is usually run once per week
as a full backup, and all the times in between as an incremental backup.
When run as an incremental, dump backs up all the files which have
changed since the last incremental backup of the same level. Again, look
at the man page for dump which explains it fairly well.

Steepness is an illusion caused by flat things leaning over.
