Re: What backup scheme do you use?
I use a combination of rsync & cron as well as simple copy and paste.
I have a desktop and a server that I use to keep copies of my files on. I've recently upgraded them both to gigabit ethernet and it makes my backing up much quicker.
I setup cron and rsync to copy the "Documents" folder on my server (which is kept up to date from my laptop with copy and paste) to my Desktop's "Documents" folder every morning at 4am.
Every Monday at 4:30am I've set up my crontab to sync my ~70GB of Music from my server to my desktop.
I find this to work very well, runs in the background and I have nothing to worry about.
I also (about monthly) will plug in an eSATA drive (1TB) and exactly mirror the contents of the 1TB drive in my server with all my extra data.
This way I've got at least 3 local copies on my network as well as an external copy in case it hits the fan as they say.
