Any particular plaform? Amiga 500?

xp, on a slow computer. Looking to backup a friend’s growing photo collection. They bought an external hard drive and are looking for a backup of their data before upgrading PCs.

A quick look around and I uncovered DeltaCopy, which is described as:

… an open source, fast incremental backup program. Let’s say you have to backup one file that is 500 MB every night. A normal file copy would copy the entire file even if a few bytes have changed. DeltaCopy, on the other hand, would only copy the part of file that has actually been modified. This reduces the data transfer to just a small fraction of 500 MB saving time and network bandwidth.

In technical terms, DeltaCopy is a “Windows Friendly” wrapper around the Rsync program…

BTW… rsync is basically the standard utility to which unix-based backup programs compare themselves to (or are themselves just a wrapper around). So… DeltaCopy sounds like A Good Thing to me.

VoodooLogic's avatar has jaback8 – a free java based backup utility program. It’s not open source, but it is freeware. Will try that if nobody has a favorite.
Thank you.

@VooDoo, “xp, on a slow computer” + Java… well, it ain’t gonna be zippy. Java can be a bit of a hog, depending on the quality of code in play.

DeltaCopy sounds unique in that it’ll perform partial file copies. Haven’t seen that, even on some of the more expensive enterprise-level backup utilities. Figured with your friend’s slow PC, any boost will help.

Anyway, there’s a rich selection of choices out there. G’luck!

I think it’ll be cool. It’s a java front end for essentially, copy and paste on a schedule.
