Let said the nas is 100GB and 75Gb is used. I have two drives as backup but it only have 50GB each. Is there a way to use rsync to copy 50GB to drive A and then compare to Drive A and copy the rest to drive B? If rsync can't do it does anyone know how to do it.
Or how you usually backup files when the nas have bigger space than the backup hard drive?

Re: Compare to one drive and copy to another drive
I would look on ebay for a larger drive. 1 & 2TB drives are beeing swapped out for larger so you can find one for a great price.
Keep an eye on the SMART disk reports and you will be fine.

Re: Compare to one drive and copy to another drive
That's not the point.
I don't like to buy used disk because well it is used and short warranty. I can get disk at best .03C per GB when the store has special sale. On ebay, last time i checked is .035+ per GB with short( 30or90day) or no warranty. ?Pay more with less warranty ?
If i use the --dry-run option will it generated the list file that will be copied? Maybe i can save that list to a text file then use the --include-from=FILE to a different destination.
Edit:
Search on ebay . You're right there are some good deals on ebay. There are WD Black around .03 per GB and it still in warranty. When i said
