Modular backup
Cake 4.18.2 (fdroid cake repo) Android 14 OnePlus CPH2399
Just has to backup seeds and private keys, theme settings and other miscellaneous.
21mb???
It's not just backing up seeds and keys, it's also backing up synchronization and blockchain data so you don't have to resync your wallets all the way (For Monero this can be a LOT of data)
I didn't look for a blockchain snapshot.
Optionally I wish a skinniest backup, like 257 kb. I am just to add it as attachment in my password manager.
It doesn’t matter the synchronization issue. I only have the task of not losing assets and hold them in an extremely compact backup.
Maybe a modular backup solve this issue. So that the user can building its tailored backup according with its needs.
