Backup Settings

Backup Settings

Backup Policy Assignment Mode: "Hierarchical" is the default and currently the only mode available.
Max. Concurrent Backups Reading Source Disks: The number of VM disks that can be read at the same time. You can increase or decrease this number depending on your network connection. The default is 3.
Max. Concurrent Backups Uploading From Local Cache: If you are using local caches, the HubStor Backup Service will save the backup to the local cache, then read the backup from the local cache when uploading to HubStor. You can specify how many backups are uploading from the local cache. You can increase or decrease this number depending on your disk performance. The default is 3
Default Backup Naming Format: The backups are automatically named using the current date and time. You can specify whether you would like to use UTC or local time formats. The default is UTC.
Auto-Enable VMs for Incremental Backups: Check this box to allow the HubStor Backup Service to automatically enable the settings required by your backup source to allow incremental backups. eg. "Changed Block Tracking" in VMWare.
Allow Non-Quiesced Snapshots: Quiesced snapshots force the guest operating system to place applications or files in a state suitable for backing up. The HubStor Backup Service will always attempt to take a quiesced snapshot first. Enable this option to allow non-quiesced snapshots if the quiesced backup fails.
Treat Non-Quiesced Snapshots As Warnings: Enable this option to treat quiesced snapshots as warnings in the HubStor Backup Service user interface and in notifications emails. Disable this option if quiesced snapshots are expected for this VM and you do not want to see warnings.

Business Hours

Your backups will run automatically during non-business hours. Uncheck a day to indicate that there are no business hours and backups can run any time that day.


Currently, no options are presented on this tab.


You can specify a semi-colon delimited list of smtp address to receive notifications. You can enable Summary, Error, and Warning notifications in this pane, and exclude Unprotected VMs from the summary email.
The options for summary notifications are Never, Hourly, Daily, Weekly, Monthly.


These settings should only be modified with the assistance of a HubStor representative as they will affect performance during restores.
