Configuring advanced storage options
You can set advanced storage-related options for the primary or secondary backup storage in your environment.
Procedure
To configure advanced options for your backup storage, complete the following
steps:
- Configure the advanced options.
Figure 1. Manage backup storage advanced options. 
- Concurrent stream limit for copy to archive object storage: This value defines the maximum number of concurrent streams that are used by this backup host when you are copying data to archive Object Storage.
- Concurrent stream limit for copy to standard object storage: This value defines the maximum number of concurrent streams that are used by this backup host when you are copying data to standard Object Storage.
- Concurrent stream limit for replication: This value defines the maximum number of concurrent streams that are used by this backup host when you are replicating data to other backup hosts.
- Enable Transport encryption: Select this option to
enable encryption of backup data while it is transferred to or from the vSnap Server. For more
information about transport encryption, see Transport encryption.Note: By default, this option is disabled to preserve the legacy behavior and also to ensure that backup and restores can continue seamlessly when updating vSnaps.
- Interval in seconds between volume/snapshot deletions during space
reclamation: This value defines the interval in seconds between successive deletions of
volumes or snapshots on the vSnap server when space is reclaimed following a run of Maintenance
jobs. Lowering the interval allows space to be reclaimed more aggressively, particularly when a
large amount of data has expired in bulk.Important: Aggressive reclamation can put input and output load on the vSnap pool which can result in slower performance for other concurrent workloads.
- Retrieval tier for restore from AWS archive object storage (Bulk, Standard, or Expedited): This value specifies the retrieval tier that is used by this backup host during restore operations from Amazon Glacier archive Object Storage. This value must be specified as Bulk, Standard, or Expedited. The retrieval tier can be modified to achieve faster restore operation times at the cost of higher data charges. For information about the available retrieval tier options and associated pricing, see the Amazon Web Services documentation.
- Concurrent Backup: This option specifies the maximum number of parallel
backup streams to the host when multiple jobs that run concurrently. For application backup
operations, each database is treated as a single stream. For hypervisor backup operations, each
virtual disk is treated as a single stream. The concurrent backup options can be used to prevent
multiple or large SLA policies from sending too many data streams to a small backup host that cannot
accommodate the load. To reduce processing time for backup operations, set this option to one of the
following options:
- Unlimited: an unlimited number of concurrent backup streams can run.
- Pause: to pause the use of this backup host. Jobs attempting to utilize this backup host will pause while this setting is selected. This option should be used in situations where the backup host requires emergency maintenance and will temporarily prevent it from being used by any jobs.
- Limit: to set a maximum limit on the number of backup streams that can run concurrently. Enter a numerical value specifying the maximum number of concurrent streams.
- Disable New Applocation: Enabling this option will make is so that the vSnap server will not be used for new storage application for virtual machine (VM) backups. Existing virtual machine backups will continue using the vSnap server. If a virtual machine backup requires new storage, it will not use the vSnap regardless of the remaining free space or VM allocation setting for the assigned site.
Tip: When you change an option value, the new value is applied when you click into the next option field. Alongside the updated option, the following message is displayed,
