** BitSilo 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. ** Create a full backup to save all the specified files; create an incremental backup to save only those files that have changed since the last backup. ** Exclude files from the backup using any part of the file folder or name, or using a filter expression. ** Restore files from any backup using a flexible query language to find files. ** Verify (compare) files in any backup against the original source files, either automatically after each run, or at any later time. ** Backup files can be stored in a folder, in a 'Silo' format for efficiency, or in a zip file (zip size limited to about 1.8 GB). ** Automatic cleanup of old backups with flexible rules governing which recent backups to keep. Lock a backup run to prevent cleanup from removing it. ** Backups and source files can reside on any addressable network share if desired. ** Recognize removable drives by volume serial number, even if the drive letter changes.
