.zab contains all including the .zbk. For only network recovery .zbk is faster and safer as it does not touch the automation part.

Funny, Polto wrote you can restore it from backup, you wrote you have the backup files.
So, sometimes its good to read and understand. I just want to give you an idea what to do......
If you read the forum or manual you will find the answer.
But I understand its easier to ask and waste other peoples time.

thank you so much @micky1500, I also restored .zbk backup and everything works fine
