We will try to put a new mirror on Singularity this week.
To answer the question above, yes, it would be possible to make an incremental periodical update between the two databases, however it is not feasible for us.
I'm going to explain a bit how the mirroring process works and why we have to prune the database we deploy on the public test servers before.
A full backup of the Tranquility database is made periodically and stored on a server. That database is then copied onto Singularity or Multiplicity - the process takes around 7 hours.
The copied database is then pruned in order to remove starbases and the moon minerals scrambled. This is done to prevent scouting on the test server of starbase locations and moon resources.
The database is further edited with the following:
* ETC accounts are edited so that they do not expire when the ETC payment runs out.
* All accounts are voice enabled.
* Agent memory is removed (standings and loyalty points).
* S&I jobs are removed (this is done in order to prevent starbase S&I jobs from being stuck.
* The market is seeded so that all market items cost 100 ISK and are in plentiful supply. At least one station per constellation is market seeded like this.
* Other adjustments for our internal use.
This process takes around 4 hours, then the database is deployed on the Singularity server. Depending on possible complications with the database copying, editing or with the server starting up after the database is deployed, the whole process can take up to 2 days.
I hope this answers your questions.

I have some more news about the mirror: the person in Operations who is in charge of moving the database copy over to the Singularity network is on vacation and won't be back until next Monday. So the mirror will not be this week, unfortunately.

To answer the questions so far:
1. The remaining Operations people are already busy with the day-to-day maintenance work for Tranquility and their other duties.
2. Copying the skill data is not enough to make a new mirror, a full database backup is needed for this.

A new mirror has been deployed today on Singularity. The mirro was taken last Thursday, on August 7th.
We would like to apologize for the prolonged lack of new mirror. The lack of human resources due to the summer vacations as well as a less-than-good synchronization with the Game Design department has caused this delay and we again apologize.
In the hopes of offering better information about the mirroring process, I have created a new thread here.

The speed changes have been rolled back on Singularity. There will be a devblog with a more elaborate explanation.
You will be able to continue testing them on Multiplicity, once a new mirror is in place there.

This discussion has strayed far from its original subject, so I will lock this thread now. Please continue the discussion about the speed changes on the feedback thread here.
