Creating Portable DiskSafes With LoopbackFS And LVM Snapshots
Author: tabination • Tags: linux, storage • Comments: 0Creating Portable DiskSafes With LoopbackFS And LVM Snapshots This is the "DiskSafe" idea used to store backups of server data. This could be used to replace physical tape volume and still provide portablility. I have found pieces of this information around the Internet but nothing putting it all together.

Back Up (And Restore) LVM Partitions With LVM Snapshots
Author: Falko Timme • Tags: linux, other, storage • Comments: 26Back Up (And Restore) LVM Partitions With LVM Snapshots This tutorial shows how you can create backups of LVM partitions with an LVM feature called LVM snapshots. An LVM snapshot is an exact copy of an LVM partition that has all the data from the LVM volume from the time the snapshot was created. The big advantage of LVM snapshots is that they can be used to greatly reduce the amount of time that your services/databases are down during backups because a snapshot is usually created in fractions of a second. After the snapshot has been created, you can back up the snapshot while your services and databases are in normal operation.

Recover Data From RAID1 LVM Partitions With Knoppix Linux LiveCD
Author: till • Tags: linux, other, storage • Comments: 5Recover Data From RAID1 LVM Partitions With Knoppix Linux LiveCD This tutorial describes how to rescue data from a single hard disk that was part of a LVM2 RAID1 setup like it is created by e.g the Fedora Core installer. Why is it so problematic to recover the data? Every single hard disk that formerly was a part of a LVM RAID1 setup contains all data that was stored in the RAID, but the hard disk cannot simply be mounted. First, a RAID setup must be configured for the partition(s) and then LVM must be set up to use this (these) RAID partition(s) before you will be able to mount it. I will use the Knoppix Linux LiveCD to do the data recovery.
