Context:
A single snapshot is about 4 GB in size. As the goal is to take monthly snapshots, the size of the database would grow too fast (~48 GB/year). This is too much data, especially since the maximum capacity of ToolsDB is 25 GB per tool.
Proposed Solution:
Keep only the detailled data for the latest snapshot and delete it for older snapshots. This will drastically reduce the total size of the database, at the cost of preventing users from making detailled queries on older snapshots. This should not pose too much of an issue as we assume that users would only care for the latest data when making work lists.
