Hi @mick-t,

The 200-300GB range seems accurate for a long running cryoSPARC instance. We have users that have reported larger sizes, but this is more rare. The database grows most proportionally with the number of jobs in the instance. Jobs create plots and figures, which are all downsampled and stored inside the database itself.

Please note that when you delete jobs, the database doesn’t release the space back to the OS; you will have to manually “defragment” the database in order to reclaim this space.
For more information on how to do this, please see this post:

Repair MongoDB Database & Reduce Database Size

Hi @Rajan, It is possible to reduce the size of the MongoDB database by using the compact command, but please note this is a blocking command; cryoSPARC will not work while this command is running. MongoDB does not release storage space back to the OS when you delete documents, which is why the storage size remains the same. First, create a backup of your database. Then, in a shell on the master node: cryosparcm restart eval $(cryosparcm env) mongo localhost:$CRYOSPARC_MONGO_PORT # will c…
