Back Up Linux And Windows Systems With BackupPC

Post date: January 28, 2007, 21:01 Category: System Views: 5147 Comments
Tutorial quote: This tutorial shows how you can back up Linux and Windows systems with BackupPC. BackupPC acts as a server and is installed on a Linux system, and from there it can connect to all Linux and Windows systems in your local network to back them up and restore them without interfering with the user's work on that system. On the clients minimal to no configuration is needed. BackupPC supports full and incremental backups, and it comes with a neat web frontend for the administrator and normal user so that backups and recoveries can be managed through a web browser. It should be noted, however, that BackupPC does file-based backups, not bit-wise backups like Ghost4Linux, for example, so it is not made for disk/partition imaging.

Using Software RAID-1 with FreeBSD

Post date: November 29, 2005, 03:11 Category: System Views: 4353 Comments
Tutorial quote: Have you ever needed a software RAID solution for a low-end server install? Perhaps you've wanted your workstation to take advantage of the redundancy provided by a disk mirror without investing in a hardware RAID controller. Has a prior painful configuration experience turned you off software RAID altogether on Unix systems?

Since 5.3-Release, FreeBSD comes with gmirror(8), which allows you to easily configure a software RAID 1 solution. While tutorials on gmirror exist, I found them to require either manual calculations of partition sizes with bsdlabel or the use of a fix-it floppy on an existing system.

It made more sense to me to configure RAID during the install of the operating system. I also wanted a procedure that was easy to follow and didn't introduce human error in the form of a math miscalculation. After cobbling together the available documentation and experimenting my way through various configurations, I came across a procedure that has worked well for me on several different systems. I also received valuable feedback from Pawel Jakub Dawidek, the author of gmirror, who gave some insight into some of the not yet documented features of gmirror.
