How to not lose decks when synchronising with ankiweb

hi i want to use my decks on my phone but I can’t synchronise my decks without losing them. If I import them on my laptop will I be able to use them again on anki (computer version?) is there any way I can avoid losing them? and is the backup plan reliable?
thank you for helping me out ( i hope i’m understandable my english isn’t great)

Did you follow the steps here?

Ps: Before syncing a doing a manual backup is recommended if you’re not 100% sure about what you’re doing.


The backup plan is completely reliable. If you follow the instructions, and save the backups away, not matter what you do, you will be able to recover your decks (you can do a dry recovery, to be sure).

However, I don’t understand why you say that you can’t synchronize your decks without losing them. What makes you think this?
