Topic: Incremental Backup

[thegallery]

OK, incremental backup means that instead of backing us, say, your entire HD all the time you just back up the files that are changed.

But I'm wondering if there is a form of backup that will also incrementally save versions of files. I have an Excel Spreadsheet I"m working on week after week, and it gets backed up every day, but I'd like it also to save  older versions of the file. Basically it would be an incremental backup, but it would not erase the previous versions of the file.

And idea if there is a term separate than 'incremental' for this, and any recommendations on external HDs that come with software that will do this?

I realize that soon the additional backup files would then take up much more space than the files in the CPU HD, but that is fine. This all came about because a friend typed a document for 4 hours saving as she went, but then accidentally saved a different file over it when she inadvertently clicked on the same name and clicked "yes" in the waring dialog box. It erased all her work before any backup was in place.

Currently I just save large Excel Spreadsheets to new names: Spreadsheet1A, Spreadsheet1B, etc.. but if would be nice if a system automatically kept older versions...

Thanks...

Corel (WordPerfect/Quattro Pro etc) used to have this option built in. I never did understand why other software houses didn't follow suit.

i though you could do this with word? I normally use checkin and out, which are tools available on linux, but am unclear about windows tools. I'll do some hunting...
