Its about time to do a backup..

[ItsMyWay]

How often do you do your back up? I think the perfect time is every 5days. What do you think? Am I wrong?

[Sevam]

I do it weekly.
you can add poll to this topic.

I backup automatically every 7 days. I used to back up daily but it put too much of a resource drain on my server

I am a bit lazy about this. Sometimes weekly, sometimes monthly or sometimes when I remember.

Time Machine is a backup software application included with the Apple OS X operating system. To use it, you'll need an external storage system, such as an external hard drive. Turn Time Machine on and it automatically makes copies of the files on your computer on a regular basis. If you lose or damage a file, you can use Time Machine to browse through the backups to recover a copy of the file.
