在Linux下使用用rsync + crontab來自動備份資料可以比美Mac下的time machine

今天總算學會使用rsync和crontab兩個指令來把系統中的重要文件檔自動備份到隨身硬碟中。總算是不必再手動用Krusader來同步資料夾了。
以後系統可以定時自動備份，為自己每天的生活多省下了一點時間，感覺還不錯。至少這樣子已經讓我的Linux FC12可以運作得像有time machine的Mac了。
雖然Mac的time machine很聰明，不需要手動，但我發現它的檔案格式並不友善（一定要format成mac格式），而且備份硬碟容量需要很多（像iMac有500G，備份磁碟容量就不能少於500Gb），不夠經濟。
