System files, such as VM Storage and Desktop DB are ignored by SwitchBack.
Under System 6 or if temporary memory is not enabled, you should increase SwitchBack’s partition size to 1 MB.
If both source and destination files have been modified since the last backup, a collision will be flagged, and the report window will display the involved files. If you elect to continue the backup, the older file will be replaced by the newer file.
