Implement a rolling file appending strategy

[remie]

This is to prevent the aggregated SQL files from becoming to large.
Symphony is quite good in executing tons of SQL statements. Putting those in a single JSON file might make it a bit too large. This will cause PHP to consume too much memory when trying to read it. That is a potential problem.

The workaround is to clear the log once in a while, after creating a fresh backup which is restored to all your environments.
