If you want your journal to stick around for a while, you might try the 3-2-1 preservation concept.
The 3-2-1 Preservation Concept:
Possess at least 3 copies
In at least 2 formats
At least 1 is far away from the others.
Purpose: To mitigate the risk of losing information by diversifying.
Example: 3 Copies – If you have a physical journal, this is copy #1. Digitally scan your journal to your hard drive; this is copy #2. Upload the scans to a cloud; this is copy #3.
At least 2 Formats – The physical journal and digital scans
At least 1 copy elsewhere – The scans in the cloud are not in the house with the hard drive nor with the physical journal.
