I’m confused. Wasn’t there a secure backup functionality? How are they “introducing” it?
I migrated my signal history twice already… Not three times, because last year the backup always failed at 9%, no matter what I tried for a week, losing the better part of a decade of messages in the process.
Maybe they fixed the functionality?
The current backup system relies on you still having direct access to your phone or a previous backup you moved off your phone yourself.
What Signal is offering now is an automatic backup system that saves an encrypted copy of your data on their own servers which you can access even if you lost your phone and never made a manual backup.
So what the are really introducing is a cloud storage service for the backups, not a backup functionality. I had my previous backups automatically uploaded in Google drive, which, despite fuck Google and all that, was convenient, secure and free.
For what it’s worth, the developers also said the backup system is completely rewritten so that now backups will work across platform and are incremental. Source: https://news.ycombinator.com/item?id=45176074
Incremental is actually a great improvement!
Exactly.
Its basically what matrix does afaik. A encrypted online key backup with a big ass recovery key for restoring that backup.
