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 you don't have to worry about open files and database connections, and you don't have to interrupt/halt services on the live partition because a snapshot is usually created in fractions of a second, so your users won't notice any disruption, and your snapshot holds consistent data. falko Sun, 15 Apr 2007 21:11:26 GMT http://www.howtoforge.com/snapshot-backups-with-timevault-ubuntu-7.10 This guide shows how to use Timevault on Ubuntu 7.10. TimeVault is a simple front-end for making snapshots of a set of directories. Snapshots are a copy of a directory structure or file at a certain point in time. Restore functionality is integrated into Nautilus. falko Wed, 19 Dec 2007 18:06:47 GMT http://www.howtoforge.com/creating-snapshot-backups-with-backerupper-on-ubuntu-9.04 BackerUpper is a tool similar to Apple's TimeMachine. It is intended to create snapshot-backups of selected directories or even your full hard drive. From the BackerUpper project page: "Backerupper is a simple program for backing up selected directories over a local network. Its main intended purpose is backing up a user's personal data." This article shows how to install and use BackerUpper on Ubuntu 9.04 (Jaunty Jackalope). falko Mon, 27 Jul 2009 10:55:41 GMT http://www.howtoforge.com/creating-snapshot-backups-with-flyback-ubuntu-7.10 FlyBack is a tool similar to Apple's TimeMachine. It is intended to create snapshot-backups of selected directories or even your full hard drive. From the FlyBack project page: "FlyBack is a snapshot-based backup tool based on rsync. It creates successive backup directories mirroring the files you wish to backup, but hard-links unchanged files to the previous backup. This prevents wasting disk space while providing you with full access to all your files without any sort of recovery program. If your machine crashes, just move your external drive to your new machine and copy the latest backup using whatever file browser you normally use." This article shows how to install and use FlyBack on Ubuntu 7.10 (Gutsy Gibbon). falko Thu, 31 Jan 2008 17:52:38 GMT http://www.howtoforge.com/how-to-back-up-mysql-databases-with-mylvmbackup-on-ubuntu-12.10 mylvmbackup is a Perl script for quickly creating MySQL backups. It uses LVM's snapshot feature to do so. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, creates a snapshot of the volume containing the MySQL data directory, and unlocks the tables again. This article shows how to use it on an Ubuntu 12.10 server. falko Tue, 15 Jan 2013 11:19:30 GMT http://www.howtoforge.com/installing-and-using-openvz-on-debian-wheezy-amd64 In this HowTo I will describe how to prepare a Debian Wheezy server for OpenVZ. With OpenVZ you can create multiple Virtual Private Servers (VPS) on the same hardware, similar to Xen and the Linux Vserver project. OpenVZ is the open-source branch of Virtuozzo, a commercial virtualization solution used by many providers that offer virtual servers. The OpenVZ kernel patch is licensed under the GPL license, and the user-level tools are under the QPL license. falko Thu, 06 Jun 2013 12:20:41 GMT http://www.howtoforge.com/rollback-to-a-working-state-with-btrfs-plus-apt-btrfs-snapshot-on-ubuntu-12.10 This tutorial explains how you can revert failed apt operations (like apt-get upgrade) and roll back to the previous system state with apt-btrfs-snapshot on an Ubuntu 12.10 system that uses the btrfs file system. apt-btrfs-snapshot creates a snapshot of the system before the apt operation. Being able to easily restore the previous system state after a failed apt operation takes away much of the pain system administrators have to deal with normally and is one of the greatest features of the btrfs file system. falko Sun, 25 Nov 2012 12:02:59 GMT http://www.howtoforge.com/virtualbox-creating-backups-and-clones-of-running-virtual-machines-no-downtime-with-lvm-snapshots If you use LVM volumes for your VirtualBox VMs, you can create backups and clones of a running VM without shutting it down. This tutorial shows just that: using LVM snapshots to create backups and clones of running VirtualBox VMs without downtime. falko Thu, 26 Jul 2012 09:01:03 GMT
