openSUSE and SLES uses btrfs as it's default filesystem and configured snapper to automatically create filesystem-level snapshots.

These disk snapshots are created periodically via cron and whenever you make changes using YaST2 or zypper.

It is beneficial as it provides fallback mechanism in any event of failure but requires additional disk spaces that not everyone could afford. Snapshots will be created even if the disk is almost full in older systems. However, newer versions of SUSE will automatically disable snapper's automatic snapshots when the root disk or partition is smaller than 16GB. In virtual machines, it will quickly fill up the small default disk size that's allocated.

Step-by-step video guide:

Remove snapper plugin for zypper

snapper-zypp-plugin is a snapper plugin for zypper. It will automatically create a system snapshot whenever software packages are installed, removed or updated via zypper. This can be circumvented by removing the plugin via the following command at the terminal:

> sudo zypper remove --no-confirm snapper-zypp-plugin
Loading repository data...
Warning: No repositories defined. Operating only with the installed resolvables. Nothing can be installed.

The following package is going to be REMOVED:

1 package to remove.
After the operation, 9.8 KiB will be freed.

Disable snapper's timeline snapshots

Timeline Snapshots are disk snapshots taken on an hourly basis with old snapshots deleted based on a policy. This is disabled by default. You can disable timeline snapshot for snapper if it's somehow enabled by following these commands at the terminal:

  1. List available available snapper configs.
    > sudo snapper list-configs
    [sudo] password for root: 
    Config | Subvolume
    root   | /
  2. Disable timeline snapshot for specific config.
    > sudo snapper --config root set-config "TIMELINE_CREATE=no"

Disable YaST snapshots

A snapshot is created when configuration changes are made via YaST. It can be disabled via these steps:

  1. Open YaST configuration file using your preferred text editor with root permission.
    > sudo vi /etc/sysconfig/yast2
  2. Search for USE_SNAPPER and set the value to no.
