How to set up back up on CentOS7 hosting plan
 

I will be getting into a 4GB RAM and 1TB storage space dedicated hosting plan at ovh.com. I want to work on an xxx tube / picture site (all videos and pictures hosted on the server), and something like a big Wordpress multisite later on. I will be also migrating another Wordpress multisite, relatively small pinterest clone website (around 30GB of storage spaces used for it so far) and a vBulletin forum to this plan.

I read quite a lot of good Linux books, but in general I am fairly new to working on this.

Where would I find good info on how to set this up on the Internet, or what book / books could I use? I guess the best way to go would be to back everything up, including all the video and picture files, in case something gets deleted. If I use less than 500GB of storage space I can back things up to the other part of the hosting, but if I exceed this, would I need to get another hosting plan (lets say 1TB)?

I mean, how would you set this up? I want to have something very good / the best / modern, the best and most standard way of doing this, lets say. Also, take into consideration the fact that I am new and I can mess something up, so two separate methods of backing up (or three) could be good, for this.

What keywords would I research, and how would I get this to work?

I will add that I would like to do if for free, or at least spend money only on another hosting plan, if this is necessary.

Thanks.

Would this sound like what I need to do here?

If less than 500GB used, use the other half of the hosting plan and copy data there. If more than 500GB used, get another 1TB hosting plan, and copy the data there. Use rsync and incremental backup (I read about doing it like one month - one week - one day type of thing; at any point, I can get to the full set of backed up files that are like one day old, at the most with this, and it does not take that much storage space).

Is this correct? What else could I do here? How would experienced people work on something like this? Like I said, I cant afford to mess anything up and I am a beginner.

Thanks.

Not much experience with backing up web servers. You can always use tar but it's not incremental.

I'm still searching around for a better solution.

This is a pretty interesting read:

Maybe Duplicity?

I did not look at the answers yet, but I will add that I could use compression too. So something like incremental + rsync + compression. I am fairly new, but I can set up whatever may be needed, including bash scripts. I can figure everything out. So the best solution can be advanced too (as far as preparing it) and I can get it to work.
