Deleting Users or Computers from the DLO Administration Console can take a long time to complete

Problem

User or Computer deletions, carried out from the DLO Administration Console, can take a long time to complete;  i.e. days\weeks.

While they are being processed or waiting to be processed, the User or Computer will show as 'Delete Pending' in the DLO Console, but will be removed once the deletion has completed.

Note: While deletions are being processed, Automated Integrity Checker (AIC) and Garbage Collection processes will not be able to run.

Error Message

Not Applicable

Cause

This is due to the number of dedupe chunk records that need to be processed in the user's UserHashStore.db. 

Dedupe in DLO only stores unique chunk data once and any other user that shares that same data, adds to the reference count for that chunk, in the dedupedb.
When a user or computer is marked to be deleted and uses a Dedupe enabled DLO Profile, their backup data has to be individually reviewed, to remove their association to the data chunks and if they are the only user associated, that data chunk can then be flagged to be deleted. This process can take an extended period of time, if users have a lot of data stored in dedupe, as chunks are reviewed one-by-one and, if multiple users or computers are marked to be deleted, data for only one user or computer can be processed at a time.
