Topic: e-mail backups

[Bob Jenner]

Hello all,
I have an interesting request I am hoping someone can help me with.

I have a client that uses SME (5.5 sp2) as their firewall and email server. They want to be able to create a backup file (tar?) of each users email (clients are setup for IMAP so all email remains on the server and is accessible by webmail).

I would like to create a script to be run by cron to autocreate a seperate email backup file per user (to make sure I don't exceed the 2GB file size limit). I have done this already, but only a single file for all users.

How can I setup the script to traverse the directory and create a seperate tar file for each users directory, then copy them to /mnt/smb/Mailbackups/ which is a SMB mount of a W2k server with a tape drive.

I hope this is clear enough. If anyone has questions, please email me directly at
bjenner@tndi.net.

Thank you all,

Bob

Good idea, here is the script you want, I just wrote it because I figured I could use it too  I've not done a great deal of testing, so if you encounter any bugs let me know.  Note that none of the lines should wrap, if they wrap on the screen be sure to fix that.

Just slap this in /etc/cron.weekly or /etc/cron.daily and be sure to chmod +x the file.

Please let me know if you encounter any bugs.

Found a bug, change:
    unlink($backup_directory . "/" . $backup_file);

To:
    unlink($backup_file);

FYI, the User Manager panel addon gives each user the ability to back up their own data (as well as lots of other useful stuff).

[JBaker]

installed the User Manager panel addon  but only have options
for changing password and/or email delivery (fwd/local/both)

where is/are the backup option(s)? is there a later version of this that gives these options (my rpm =
e-smith-userpanel-pkg-0.0.1-1.noarch.rpm)

Thanks
