Similar to a system restore point on a Linux server?

Question

linux

Is there an analogue of system recovery like Windows for a Linux server?

Answer 1

The closest analogue in my opinion is file system snapshots

1. LVM supports snapshots for any fs, but they require a separate partition to store changed data
   
2. ZFS or BTRFS also support Copy-on-Write snapshots and do not require separate storage
   

Note that snapshots != backups. Backups are also necessary. But backing up snapshots is easier and safer in terms of data consistency.

Answer 2

Restore points are required on Windows as it is a highly coupled and closed system.
Linux allows you to simply backup - everything, including system settings. After copying the files back, the system will not go blue screens and failed activations.
Well, for the lazy, but gambling - you can use a file system on the system partition that can take snapshots ...

Answer 3

Backups, disk snapshots.
How exactly - there are a lot of ways, this is a minimum for a Khabrov article.

Answer 4

Most likely it will work only on the zfs file system.
Commands for the console look in Google.
You will most likely have to wean yourself from the GUI for such things, almost always servers with Linux are administered through the comm line
