HP 3PAR Recovery Manager Software for Microsoft SQL Server Licenses - Manual (Page 59)

NOTE: HP 3PAR VSS Software waits up to 10 seconds for a virtual copy operation; and this
interval can not be configured. In most of the cases, 10 seconds is a sufficient interval to successfully
create a virtual copy. However, in some circumstances under very heavy loads, 10 seconds may
not be enough time, and the virtual copy might fail on this attempt. This failure is a VSS framework
requirement on Microsoft’s part.
If such a failure occurs, VSS does not automatically retry the shadow copy creation. You must use
the Recovery Manager GUI or CLI to reattempt to create the virtual copy.
During virtual copy creation, the system creates a backup document in XML format. This document
contains current system information and can be used for restore purposes.
NOTE: The snapshot volume set is limited to up to 64 volumes. In other words, each database
(under database-level operation) or each instance (under instance-level operation) can spread over
a maximum of 64 volumes.
NOTE: You can only perform database- or instance-level operations if you have system admin
permissions for SQL Server.
Recovery Manager creates copy-only backup for availability databases on secondary replica.
You can execute concurrent virtual copy creation jobs through multiple Recovery Manager CLI
instances. In this case, HP 3PAR Recovery Manager for SQL queues the requests to the VSS so that
all the requests are serviced without any failure.
HpRmCli Sql deletebackup
SYNTAX
HpRmCli Sql deletebackup -s <SQL server> [-i <SQL instance>] [-d
<database>] -t <timestamp>
DESCRIPTION
The HpRmCli Sql deletebackup command removes the specified backup entry from the

Protector entry, nor does it remove the actual images backed up by the backup process.
PARAMETERS
The following options are supported:
-s <SQL server> SQL server to which the backup belongs.
-i <SQL instance> Optional. The SQL instance associated with the database. If not
specified, MSSQLSERVER (local) is used as the default value.
-d <database> Optional. The database-level backup to be removed. If not specified,
the instance-level backup is removed by default.
-t <timestamp> The backup entry timestamp.
EXAMPLE
The following command deletes the backup timestamp 020405162103:
HpRmCli Sql deletebackup -s server1 -d db1 -t 020405162103
