Linux: organizing periodic backups

Question

linux

I'm going to put the system + / home (application settings and current documents) on the SSD, and store all sorts of heavy files on the HDD. But I would like to protect myself from scaling the SSD. To do this, I plan to organize a backup from SSD to HDD. Ideally, I would like to back up the entire system once a day, and back up certain folders (with documents) as often as possible (it is desirable to track changes and synchronize upon changes made).

Q: What tools should be used and how?

My SSD: Intel 320 series 80 GB.

Answer 1

rsync, man rsync. Able to save rights and owners normally (like even including selinux), avoids squandering on hard and soft links, partial synchronization.

Answer 2

tar, gzip, crontab

Answer 3

LVM snapshot + ionice + any copy utility

Answer 4

Weekly backup with a simple tar+gzip of the system, and store all important docks in dropbox/owncloud/etc.
And the chances that the HDD will die are higher than those of the SSD, especially Intel, this is especially important for laptops.
