Performance Settings

Concurrent Queued Tasks

Set maximum concurrent tasks that are initiated on-demand (Restores, Downloads, Snapshots, Quick Clone) [ Set 0 for unlimited ].

Concurrent Scheduled Tasks

Set maximum concurrent tasks that each job type (Backups/Clones/Reindex) should run simultaneously [ Set 0 for unlimited ].

This value applies per type (Backups/Clones/Reindex).
For example, we created 3 backup jobs, 3 Clone job & 3 reindex jobs - Setting the queue value to 3 will pick up 3 jobs at the same time per type, so eventually, 9 total jobs (3 of each type) will run together.

Update Incremental Backups Sizes

**High usage of IO on the backup server**- Activate only when needed, this will execute "du" command on the SSH and Local backup servers to calculate folder sizes.

Restore Server Load Limits

The default is 5, If the server load reaches this limit, restore process will wait for the load to go down. [ To disable insert 0 ]

Restore sleep time

The default is 60 Seconds, Time to wait between restore points, could be useful when server load is high (when creating/packing an account). [ To disable insert 0 ]

The default is 1 Day, select the number of days you want to keep downloads on your server. [ To disable insert 0 ]
