Good systems administrators know that implementing a robust backup procedure is one of their most important duties. Unfortunately, it's also one of the most complex and least fun. When the phone rings and there's a panic-stricken user on the other end who has just lost a crucial document, you need to be confident that you can promptly recover his missing files. Failure to do so can bring about a speedy end to a promising career in systems administration. So what's a budding sysadmin to do? Download the latest release of Bacula and watch those backup woes disappear into the dark of night.
So you just bought an external hard drive for backups. Now, with what filesystem should you format it? Ext2? FAT32? No matter which one you choose, there are trade-offs to consider.
Backing up data stored in a MySQL database is an important issue for anyone running a blog, wiki, or any Web-based application that relies on the popular database engine. Many MySQL management solutions allow you to export database data as an SQL query, but if you are looking for a dedicated MySQL backup tool, phpMyBackupPro (pMBP) is your best bet.
Perhaps the number one reason why people neglect to back up their desktops is the lack of workable solution. It can be difficult to find a method configurable enough to suite everyone's needs. One promising answer may be Restore, an application for enterprise and data center backup for Windows, Mac OS X, and Unix/Linux systems. It is GPLv2-licensed and freely available to download as a set of Debian/Ubuntu packages, virtual machine, or 455MB installable live CD.
DV and MiniDV camcorder tapes can be used for more than just storing audio and video recordings. If you have a camcorder and a FireWire connection to your computer, you can also use them to store files.
No matter what Linux distribution you are using, chances are you'll find more than one graphical FTP client in its repositories, but if you are looking for a powerful command-line FTP tool, your best bet is lftp. Of course, you can always use the good old ftp command, but lftp takes the task of managing files and directories using the FTP protocol to a new level. To see what I mean, let's use lftp to write a script that creates a local backup copy of a Web site.
Making periodic backups is a common task. Synbak can help to simplify it.
Managing disk space used to be a royal pain for admins and users. Running out of disk space often meant reinstalling Linux or spending a few hours with tools like Parted to resize partitions. However, using the Logical Volume Manager (LVM) tools, you can grow, shrink, and manage disk space with very little hassle.
Need a simple yet effective way to back up your laptop or desktop machine to a network-attached storage device or a network hard disk running Samba? Using Samba's smbmount utility and the grsync backup tool, you can set up a backup system that is both reliable and straightforward in use. And since both programs are available as packages for most Linux distributions, you don't have to get your hands dirty compiling from source code and fiddling with settings.
In the last two months I've been traveling a lot. During the same period my main desktop computer went belly up. I would have been in trouble without rsync at my disposal -- but thanks to my regular use of this utility, my data (or most of it, anyway) was already copied offsite just waiting to be used. It takes a little time to become familiar with rsync, but once you are, you should be able to handle most of your backup needs with just a short script.
Rsync is a command line utility traditionally used in synchronizing files between two computers, but rsync can also be used as an effective backup tool. This free and powerful tool is simple enough for anyone to use on their Linux desktop.
