I've started exploring and administrating a Linux (CentOS) server. So far I have been doing backup for server only by compressing files and directories and download them to local disks, on a daily routine.
That's manual, and it sucks because it eats a lot of disk space. Data is growing bigger and i'm not rich enough to raise it this way.
Now i'm looking for a solution that can perform backup incrementally, which means only changes will be backed up. But we can choose to return any point in the past (like Windows's restore point and MAC's time machine).
The two main things to do put in the backup file are the system configurations (users, networks, ..) and/or all or specific directories and files (/var, /home, ...)
As i googled, i found something about RSYNC, but am not sure if it can do as I expect.
If anybody here has experience with this, please let me know
Thanx a lot!
