Old thread update:
WinPenPack is offering a version: X-Areca V. 7.2.3 http://www.winpenpack.com/en/download.php?view.1327
... Unfortunately it's a bit out of date (current is 7.2.10, updated in June 2012).
Probably the launcher still works. You can test it moving new version Areca's program files to the bin
folder and overwritting the old ones.
I just found out that Areca will do incremental backups based on file changes rather than whether or not the entire file has changed. That's great news. Going to see what I can do with that for sync purposes rather than purely backup uses.
Unfortunately, the same problem is present with X-Areca (v.7.2.3) lagging behind Areca official (v.7.2.17).
By the way, if you use jPortable and some winPenPack's java-based programs (or vice versa), it's easy to share the java installation using symbolic links to save some disk space.
Can you post a little more about that?
