Jackup is a simple and easy to use backup tool made in Java. Choose two folders, source and destination. Jackup scans all the files and subfolders, and tells you what files have been changed and which files don´t exist in the source anymore.

There are three ways to compare files: date/time, date/time/size or date/time/contents. If you want to be absolutely sure that files are identical both in the source and destination, choose the last option.

Feedback about the program is very important! Send me some email and tell what you like about Jackup and what could be done better.

Jackup needs Java JRE release 5.0 to run.
