Just a word of warning... I'll be posting more information soon (doing more testing) but I would NOT rely on synctoy for anything you care about.
It's free, and that's what it's worth. It will NOT create a safe, reliable, or complete backup of your data.
When setting up a folder pair, it would seem that echo is the safest option that most people choose, but it can't truely echo files correctly. The set up information doesn't tell you that it won't check file contents to see if the file has changed, even
if it's doubled in size.
I've been using it for months with constant problems. I started digging into them again today because it won't update some files (Adobe .xmp files) even when they're clearly dissimilar. if you change the Echo options and tell it to verify contents,
it will screw up even worse. Today, it duplicated over 1600 files (i.e., created a "file_a.1, file_b.1, etc. scenario). I used a REAL program to compare the files via MD5 hash, and the files were identical. I knew they were identical anyway, because 99%
had never been changed (most were image files, or Canon RAW (.CR2) files). The problem is that Synctoy doesn't know when a file has changed and when it hasn't. You absolutely can NOT trust it.
This is just one situation, but if it can't take Adobe files, then it's worthless to me, and millions of others. So we could ask if Adobe is doing something so Synctoy can't read the files? Maybe, considering Adobe writes buggy software, but it highlights
that Synctoy is NOT a real program for 2011/2012; it's a free utility that works like a program from a first year college student.
If it only gets 80%-90% of the file sync right, then it's 100% NOT recommended for anything more than a toy, as the name signifies...
