I would like to backup my mail directory on a USB key. However, my IMAP has a strange naming convention that something include a colon (:) character. Since the USB is in a window format, rsync fail to create those file. Is there a way to replace the colon character by an underscore when running rsync? (Or to do the same synchronization with another tool?)
Just a few point that I clarified in the comments :
- This is a worst case scenario backup, I would like to be able to read it on a windows machine without installing anything.
- I got a lot of data that stay constant. So I save a lot of time if I have a tool that just copy the newer files.
- I am not looking for a rewrite of rsync. I am looking for a existing tool that can be used out of the box.
