Linux is a popular operating system for many organizations. And unlike Windows and other operating systems, Linux is publicly open and distributed by a number of different companies. Because of this, Linux backup is different than backup on other operating systems, and can pose a number of different challenges to users. According to Brien Posey, a freelance writer and former CIO, Linux backup can be confusing because "there are so many...
different flavors of Linux. There are many different versions of Windows, too, but all of the Windows versions were written by the same company. Additionally, Linux is extensible, and there are numerous add-ons for Linux that are open source in nature, and freely available," he said.
W. Curtis Preston, an independent backup expert and executive editor at TechTarget, also pointed out that "Linux has no built-in snapshot driver system like Window's VSS. It is up to you and your application to make sure that it is in a proper state when the file system is backed up," he said.
Furthermore, choosing a Linux backup tool can be confusing. Since there are so many versions of Linux, the number of Linux backup tools increases, and the choices can be daunting. "There are many different criteria that go into choosing a backup application," said Posey. "All of these criteria really boil down to picking a backup application that will meet your needs. This is especially important in a cross-platform environment, because not every backup application can back up every remote system." Preston added that you also need to look for "automation, scalability and good reporting" in a Linux backup tool.

Backing up Linux servers can be daunting to small- to medium-sized businesses (SMBs), who may not have as well-organized a data backup strategy as large enterprises. This article from SearchEnterpriseLinux.com describes three backup solutions SMBs can create for Linux systems. First, you can use rsync, which helps with the remote synchronization of files. Second, you can configure an automatic SSH login. Once this SSH login is created, it will automatically connect with your public/private key pair, and then generate an encrypted package. Third, you should schedule your backup job using cron, which will automatically synchronize your data daily.

Last year, Symantec Corp. released a new version of its bare-metal restore software that added support for Linux servers. Linux was the first non-Windows operating system to be supported by Backup Exec System Recovery (BESR). And BESR offers one centralized management platform, the System Recovery Management Solution.

Most people know instinctively to back up critical data on their Linux servers, however, one Linux backup procedure that might be overlooked is backing up your master boot record (MBR). The MBR is an essential part of your computer that contains GRUB as well as the partition table. It's essential that you back it up. In order to make a full backup of the MBR, you need to follow three basic steps: find your master boot record on Linux, back up the MBR using the dd command, and restore the Linux master boot record if you are having problems related to the MBR. Read the full article for all the details on backing up the Linux master boot record.
