The real-time scanner and scheduler make the program very hands-free.You can also specify what to do with old files (delete, recycle, or version), and whitelist/blacklist files. Since you can specify how you want to compare files (time, size, or content), you can choose between quick and thorough backups.Instead, you can make a donation to unlock additional features.

The program is not only free and open source, but it doesn't even include ads or adware.

After using it for awhile and realizing how amazing it is, I also stopped using SyncToy, which was a similar program.

Looking for fastest way for the program to run and deleting and copying every file doesn't seem to be it.Īgain, I'm still new at this.I found this program after searching for a replacement for the default backup software of my Synology NAS which was far too slow. Technically they are but I would have thought they were exact copies. From what I recall, after 'compare' it said for each file the ones on left were 'newer' But I believe when I did compare and then mirrorsync it deleted and created all the files, as in ones I didn't touch on external. It seems like the external drive folder on the left and the NAS on the right, that 'mirror' would do what I need. I just started messing with it, did some tests. On synology forum, Freefilesync was recommended. lol) and bring it home to sync to NAS, probably once a week. I will be doing all my organizing, editing, cleaning up of files that are on the portable hdd offsite with my laptop(lots of free time at work. I used USB Copy package to copy everything from NAS to a portable Hdd. Standard home user stuff) transferred over. I recently bought a Synology NAS and have all my files and folders(pics, Vids, music, docs.
