I am thinking about setting up this backup system for my PC

[radge]

Hello, I have a tower with a 512gb SSD for the OS and then a secondary 2TB HDD.
I also have two external HDDs of 500gb and 1Tb respectively.

The idea I have is to make full weekly backups of the files I need (photos...documents...code...) and then incremental ones every day at night.

For the full ones, the idea would be to save 3 or 4 copies that fit on the disk where I will make the backups and then the incremental ones for each week, so if I start this on February 1st it would look something like this

1 February full backup
2,3,4,5,6,7 incremental backup

8 February full backup
9,10,11,12,13,14 incremental backup
...

And this process 4 times, then delete the first one and start over (rotation)

As for software, I had used Cobian but as I see it's a bit outdated, I was thinking of using "Uranium backup" or "Iberius backup"

What do you recommend?
Thanks

Hello:

Which disks are you backing up to? Because with the hds space you have, I don't think it will go very well. Calculate that if you copy the 2Tb one to the others, I don't know if the program will let you send it to different disks. Mostly because the program won't see them as a single disk. Back in the day, there was Linux LVM, which was a software RAID for computers to which many disks were added periodically, but you didn't want to relocate the data every time you did it. But I'm talking to you from 15 years ago. Now I don't know if it's still being done. Mostly because the price of hdds has dropped considerably.
For what you ask, the first thing will be to get disks of the same size, set up a raid, and then use the program you want for backups. One that I used a lot in its day is this one, with a tutorial from a forum colleague:

Let's see if this one serves you.
