Hello
I plan to make increment backup for my home dir.
It's currently in the size of 1xx GB.
besides rsync, do you know any other software/service for increment
backup?
chiark-backup and amanda both work well. Chiark is good for a small network and should work well with your requirement to backup a single home directory.
What are you backing up to? I use rsync to backup to a USB hard drive and it works well, fast and simple.
Thank you.
