  • Creates timestamped backups for files and directories you specify.
  • Create multiple backup sets, each containing a different set of files or directories to be backed up on a daily/weekly/monthly schedule.

  • Exclude files from the backup using any part of the file folder or name.
  • Flexible management of disk space used by backup archives.
  • Restore files from any backup using a query language to find files.
  • Backup files can be stored in a BitSilo "Silo" format for efficiency, or in a normal folder, or as a zip file.
  • Automatic removal of old backups; cleanup rules govern which recent backups to keep.
  • Verify (compare) files in any backup against the original source files, either automatically after each run, or at any later time.
  • Use the free utility SiloExplorer to access any BitSilo archive (from any computer) and extract files from it.
