Backup Modes |
Warehouse offers 4 backup modes which help you solve a variety of backup of scenarios on a task-per-task basis. The following explanation uses the terms source and destination which refer to the source folders and destination folder respectively.
Update
Archive
Changes to the source are transferred incrementally to the destination and stored by date like Apple's TimeMachine. Although it may appear there are hundreds of duplicate files in each archive only new or modified files will occupy disk space. For example if you had a source folder containing 1GB of files which was archived 5 times without adding or removing any files the 5 archived folders will still collectively occupy only 1GB of disk space despite each containing hundreds of seemingly duplicate files.
Note: As of 10.6 the Finder does not always report the correct size of archives in the Get Info window (command-I).
Synchronize
Any changes made to the source (added files/folders, modified files etc...) are transferred to the destination. Any files on the destination that do not exist on the source will be deleted.
Warning: please use this mode with caution as it could lead to data lose if used carelessly.
