Huge Time Machine backup

[jeykey]

I´m running Mojave 10.14.2 and my latest Time Machine backup is asking for 130GB. I´m sure, at most, I´ve only incremented about 6/7 gb. So why such a huge backup ? First time this happens to me.

Probably has something to do with encryption or something. What format is the drive with Mojave on it?

It´s in APFS and I don´t use any kind of encryption.
