## Symptoms

- * `backup` command fails with the following error:

  ```
  
  [Expert@:0]# backup
  Are you sure you want to proceed (y/n) [y]? y
   
  Creating backup package...
  -rc=-10  line=180
   
  sh: line 7: [: too many arguments
  ```

* backup debug showing the following errors:


  `
  [DATE TIME]: Info: 'generic_backup': Executing `&1>   
  [DATE TIME]: Info: 'generic_backup': Execution Failed.   
  [DATE TIME]: Info: 'change_to_root_dir': Changing to directory /var/tmp   
  [DATE TIME]: **Cannot complete the backup process due to package compression errors.**   
  [DATE TIME]: Info: 'unlock': Removing ..

* Running the same failed command from the logs, using the full path, completes the backup. 
  The syntax would be similar to the following:  


  `tar -C / -zcvf /var/log/CPbackup/backups/backup_mdms.com_28_Sep_2017_07_35.tgz --ignore-failed-read -T /tmp/temp_tar_include_7269.txt -X /tmp/temp_tar_exclude_7269.txt`

## Cause

1. In some case the new /bin/tar version (TAR 1.26) is caussing issues.  

   **OR**   

2. There is not enough space under the */var/log* partition.

Check Point recommends to always upgrade to the most recent version ([upgrade Security Gateway](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doShowproductpage&productTab=downloads&product=435) / [upgrade Cluster](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doShowproductpage&productTab=downloads&product=428) / [upgrade Security Management Server](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doShowproductpage&productTab=downloads&product=184) / [upgrade Multi-Domain Security Management Server](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doShowproductpage&productTab=downloads&product=166)).

If you wish not to upgrade, downgrade to TAR version 1.15.1. You can verify your TAR version with this following command:

*\[Expert@MGMT-test:0\]# tar --version* *tar (GNU tar) 1.15.1* **OR** [contact Check Point Support](https://www.checkpoint.com/support-services/contact-support/) for a 'cpbackup_util' fix package  

**OR** remove unnecessary files to free disk space in the */var/log* directory.
