Description (partial)

Customer is requesting that we increase the number of available snapshots.  the global-limit value is set to 50.  This number is insufficient for their needs as they have multiple tenants and are doing individual tenant backups.  The request is to keep the snapshots onboard to speed in recovery time should users make configuration errors.  200 to 300 would be a target number.

Symptom:
Customer has 20+ tenants (adding more daily)  and would like to keep a few snapshots at least a days worth @ every 8 hours.  This would be at min 60 and if they wanted to do full backups a larger number.  Disk space is not a concern as the tenant backups are not very large.  The customer would like to keep the snapshots on board for ease of recovery.  When snapshots or configurations are stored off disk it is too difficult for users to import and recover.

At present some backups are failing as there is no room to write new files as several new jobs kick off at the same time for backups and the directory already has 50 files in it at a given time.

Conditions:
In this case customer is trying to maintain onboard snapshots for easy rollback.  This customer has 20+ tenants and is adding more at a rapid pace.  They want to maintain several 8 hour window backups, so as tenant admins make changes they have the ability to quickly rollback any changes that could have been service affecting.
