Macrium Reflect provides multiple Backup Plan options to create backup cycles in days, weeks or months that allow you to pick when you want your backup definitions to run and whether they should be Full, Differential or Incremental backups. Scheduled backups can run independently of whether anyone is logged into the computer. Macrium Reflect provides an easy 3 step approach to editing backup plans for a backup definition: Options define whether to apply the retention rules to all the backups in the folder, whether to run the purge before backing up, and let you define a minimum amount of disk space to retain in gigabytes (GB) before automatically deleting the oldest backup sets in the destination folder to make space available for new backups.
