yCopy2 is a backup/sync tool with multi-threading and a rich set of command-line variables.
Warning: the SYNC option will recursively delete files & folders from the destination path which aren't present on the source. Use with caution, and experiment with unimportant files first.
I've been using yCopy2 to back up my stuff for a couple of years now, but that doesn't mean the program will suit your needs. Use this software at your own risk
Due to a limitation in Microsoft .Net, yCopy cannot back up files where the source or destination path + filename is longer than 256 characters. E.g. C:\Temp\etc\etc\more stuff\(to a depth of 256 chars)\Some really long file name.doc
A network mode where yCopy2 will communicate in client-server fashion, speeding up lan backups.
Built-in scheduling to run backups at specified intervals.
