This isn’t a help request - I’m just curious about a change.
I noticed recently (around 2.0.4.x releases) that new job databases seem to be all numeric (such as 89677133708265797163.sqlite) where they used to be alpha based (such as CTPKXALMSD.sqlite).
The “global” database file is still Duplicati-server.sqlite and backups (usually created as part of a Repair or Recreate) are still timestamped (such as backup 20190106091829.sqlite).
Appends the string representation of a specified 32-bit signed integer to this instance.

says expect numbers 65-90 inclusive. Easy way to get a hint is to sort by name and read leading 2 digits. For a full-string study, one can go left to right 2 digits at a time. Breaking name in an editor may be easier.
