... in which case, a backup is the obvious answer - for all types of
storage and regardless of whether the IP uses one storage volume or two.

First backup will take hours, but if the OP uses something moderately
clever for doing backups, i.e. rsync, then subsequent backups will be
quick. Provided he does reasonably frequent backups then little or
nothing will be lost and recovery from a failed SD card/SSD/HDD will take
no longer than unplugging the dead one and replacing it with the latest
backup.

Followed by making a replacement backup - of course! But that should run
OK overnight or as a background process.
