I have a number of Xen virtual machines running on a number of Linux servers. These VMs store their disk images in Linux LVM volumes with device names along the lines of /dev/xenVG/SERVER001OS and so on. I'd like to take regular backups of those disk ima
In this tutorial we will set up a highly available server providing iSCSI targets to iSCSI initiators. Should a server become unavailable, services provided by our cluster will continue to be available to client systems.
Following on from the previous example we now want to use the extra space in the "ops" volume group to make a database backup every evening. To ensure that the data that goes onto the tape is consistent we use an LVM snapshot logical volume. A snapsh
LVM is an implementation of a logical volume manager for the Linux kernel. The biggest advantage is that LVM provides the ability to make a snapshot of any logical volume.
Here I will describe how to implement a backup scheme that I have found very robust, efficient and reliable. It enables automated backups of Xen virtual machines that each reside on individual LVM volumes using a utility called rsnapshot (which is based o
