It is important to backup your seed phrase but some people said the backup is not good online but which is true because we have seen how hackers was able to see some people seed phrase online and steal their coins.
Its a very bad idea to use any online means to save our seed for backup, they are centralized and anyone can spy into their server and fish out users informations and sensitive data against them, this will be the only means i can refer someone to use in saving his seeds for backup as already discussed on several occasions by some forum members.

https://bitcointalk.org/index.php?topic=5230920.0But I have been thinking recently that how can people in countries with natural disaster be able to backup their seed phrase offline?
I want to believe that not all countries are being affected and for the ones affected, such is prone on specific areas, most importantly, we have to consider an alternative means to using any storage means, that is, we should have at least two means where we have our seeds backed up, but using online storage is not a recommendation to consider.
