Fixing Snapshot Issues in SLES 15 SP6: Rolling Back to a Previous Snapshot

SLES (SUSE Linux Enterprise Server) 15 SP6 is a popular server operating system that provides various features and functionalities for businesses and organizations. One of the essential features of SLES 15 SP6 is the snapshot, which allows users to take a snapshot of their system at a particular point in time, enabling them to roll back to that point if necessary.

What is a Snapshot in SLES 15 SP6?

A snapshot is a copy of the file system or system state at a particular point in time. In SLES 15 SP6, users can take snapshots of their system using the Btrfs file system. Btrfs, or the B-tree file system, is a copy-on-write (COW) file system that allows users to take snapshots of their system without causing any downtime. When a user takes a snapshot, Btrfs creates a copy of the file system at that point in time and marks it as read-only. Users can then roll back to that snapshot if necessary.

Why Roll Back to a Previous Snapshot in SLES 15 SP6?

There are many reasons why a user might want to roll back to a previous snapshot in SLES 15 SP6. For instance, if a user installs a bad patch that causes issues with their system, they might want to roll back to a previous snapshot before installing the patch. Additionally, if a user accidentally deletes critical files or makes changes that they later regret, they can roll back to a previous snapshot to restore their system to a previous state.

How to Roll Back to a Previous Snapshot in SLES 15 SP6?

Rolling back to a previous snapshot in SLES 15 SP6 is a straightforward process. Here are the steps to follow:

1. Boot the desired snapshot:

2. Verify that the snapshot is the current root file system:

It's important to note that rolling back to a previous snapshot in SLES 15 SP6 will overwrite any changes made since the snapshot was taken. Therefore, it's crucial to ensure that all critical data is backed up before rolling back to a previous snapshot.

Snapshots are an essential feature of SLES 15 SP6 that enables users to take a copy of their system at a particular point in time, allowing them to roll back to that point if necessary. By following the steps outlined in this article, users can quickly and easily roll back to a previous snapshot in SLES 15 SP6.
