Logical Volume for System Files ?

TokTok · 10-01-2019, 02:06 AM

I was reading that Linux LVM allows to put different files in seperate volumes, my question-Could a Linux Distro Install place a Back-Up copy of the system files in a seperate volume to repair if dameged or altered ?
Could this run in the background in **Real Time** or at regular interval **User Specified** say every 1-10 seconds,minutes,hours or after Re-Boot to Re-set to original Configuration **Fresh Install** ?

these are two different things. I mean you can use LVM if you wish (for backup), but it is more or less irrelevant. You can make backups on regular filesystems, pendrives, tapes or LVM in [almost] the same way.
Regarding the backup of your system files: https://www.tecmint.com/linux-system-backup-tools/ (but you can look for other solutions too).

Short answer is "Yes". Have a look at snapper for LVM, or timeshift. Others exist, but primarily all rely on snapshots.

So i could make a copy of just the system files **Not the Whole Install** on a USB or DVD etc. and use when needed to replace sys files only / Correct ?
This would be the same as with Win XP you just put in the disk choose repair **Sys Files** and they were replaced with a fresh copy leaving everything else intact, can be the same with linux / Correct ?

I just checked out the link and scripts available, seems i should be able to fine something there, but could you recommend something easy to use for a linux newbe and free open source if possible ?

I would rather suggest you to try more of them and choose the one which is really suitable for you.
You can also look for other tools (like: http://snapper.io/).

A default install of Linux Mint will use timeshift that can be enabled for roll-back of the system code components. Last I looked it doesn't use LVM snapshots, but the effect is similar. See the install doco.
Probably easiest as it has been structured for new users.

Look`s like i`ll give linuz mint a try, i used it before in live mode but did not really like too much, seems better now though.
