+### Skipping tar creation
+
+The last part of creating a backup is generation of a `.tar` file containing
+all the parts. In some cases (for example, if the backup is picked up by other
+backup software) creating a `.tar` file might be wasted effort or even directly
+harmful, so you can skip this step by adding `tar` to the `SKIP` environment
+variable.
+
+Adding `tar` to the `SKIP` variable leaves the files and directories containing the
+backup in the directory used for the intermediate files. These files will be
+overwritten when a new backup is created, so you should make sure they are copied
+elsewhere, because you can only have one backup on the system.
+
+For Omnibus GitLab packages:
+
+```shell
+sudo gitlab-backup create SKIP=tar
+```
+
