Ubuntu Disk Imaging

**Zathara** · 08-04-2011

I would be able to image the SSD I have my Ubuntu Desktop installation on 10.10. Does anyone have any experience of this and can suggest tools to use? I'm looking for something ideal that can be run within Ubuntu via the command line (for automation purposes.) If I have software RAID set is retained in imaging? Anyone have any idea about this? Please if anybody gets any information or any idea about this than please provide me.

Note that LVM snapshots are in no way a backup strategy on their own, despite the help of such a strategy. Personally, I use BackupPC copy everything to an external server. It is very efficient and is set and forgets. It also allows you to maintain a hierarchy of backup so that you can restore individual files or whole, to the point in time. A bit like Time Machine in Mac OS X. To be honest, I do not bother with disk imaging on my Linux machines. It is very easy to install and restoration that I find useful image.

LVM snapshot is an accurate duplicate of an LVM partition that all data has been compiled on the LVM volume from the time the snapshot was. The major benefit of LVM snapshots is that they can be utilized to significantly reduce it’s the amount of time that the services and database backups are to be set because a snapshot is usually shaped in a split second. Later than the snapshot is created, you can back up the snapshot when your services and databases are in usual operation.

This looks great but has some problems:

As far as I can tell you need to boot into your living environment?
In your website in the limitations section stated that "RAID / fake RAID are not supported by default. It can be done manually only.”

It was unclear to me whether that meant that the software RAID configuration or the raid array itself. I would have thought that the raid configuration includes imaging without problems. Whereas imaging of a collection of elements of the matrix could be significantly more difficult!

A real image can have on a Linux system using the dd command, but I would not recommend it for the same reasons ijack said. The best thing to do is set the machine; make a tar.bz2 of the unit and the store on the outside. If you ever lose the system drive, booting a LiveCD, then reinstall the system, then the files you require and move them to places of configuration. This machine is unluckily the server so it will be the backup on an external drive. Again, it is the server and has a lot of settings that do not want to go through several times; I would like to back it up.

You must, of course, a backup. But unlike Windows, a Linux system can be a backup as a collection of files. This is much more versatile than a backup because it is easy to restore a single file, which is part of the system, or the whole system. Backup image is too large a blow to my taste, and no easier to restore a file collection. To protect against disk failure, use RAID. Any other kind of failure or disaster is covered by the backup files.
