11. Backing Up Windows Machines to a Linux Host
Adam Neat ( adamneat@ipax.com.au) kindly contributed the following script to back up Windows machines to a Linux host, using the smbclient utility. Adam says that it is used to backup Windows 3.x and NT machines to a Linux based DAT SCSI Drive.
Adam is not proud of the coding style used here, but it works. As I like to say, "If it works and its stupid, then it is not stupid".
Another Windows backup script, contributed by Dan Tager ( dtager@marsala.com), is provided below. Dan's script also backs up Unix machines via rsh, although that could be modified to use ssh rather easily.
In this script, the string 'agnea1' is the username on the Linux machine that does the backups.
