This article describes how to use backup scripts and commands and commercially available software to protect disk data securely and efficiently in a Linux environment. The backup and recovery system assumes the function of ex ante backup and afterwards recovery. In the current high-speed development of the network env

a disk image file, you perform compression:dd if=/dev/sda | gzip > disk.img.gzdd if=/dev/sda | bzip2 > disk.img.bz2That's good! Ghost has all the features.2. Partition cloningIf we don't want to clone the entire disk and just want to back up some of the partitions that hold the data, you'll need to clone a partition. As stated in the preliminary knowledge, partitioning is also a file under Linux. For examp

information has also been corrupted. Third, when the LVM structure is corrupted, the backup information is also damaged (for 1, 6 of common failures): This is the real technical problem, when the LVM structure and its backup information is corrupted, all the LV Fragment index information is all lost, the work to do is to retrieve the LV extents information for each VDI. Xen VDI is based on the VHD format developed jointly by Connectix and Microsoft, typically with a streamlined growth model

Git is currently a popular distributed project versioning system, compared to SVN has a great advantage, yesterday was thinking that you should make good use of git, so I think you can use git version fallback, etc. to do a simple project automatic backup and recovery functions. This allows you to use GIT to do project versioning and to use Git as a backup. This makes it easy to migrate, back up, and so on.Features and implementations are really simpl
