Follow these steps when backing up the file system.
  
    Backup the following subdirectories of the SkyVault Community Edition
      dir.root directory using whatever tools you are comfortable with
        (rsync, xcopy):
    - contentstore
- contentstore.deleted (optional)
- solr4Backup
Note: Do not attempt to backup the solr4/index subdirectory while SkyVault Community Edition
      is running. This will cause Solr 4 index corruption. Use solr4Backup
      instead.
