NAME

Enable-DcsDataProtection

SYNOPSIS

Enables Continuous Data Protection (CDP) for a virtual disk. This operation can also be performed on a virtual disk group.

SYNTAX

Enable-DcsDataProtection   [ -Server <String> ]   -VirtualDisk <Object>   -Pool <String>   [ -HistorySize <DataSize> ]   [ -Connection <String> ]   [ -PipelineVariable <String> ]

Enable-DcsDataProtection   [ -Server <String> ]   -VirtualDiskGroup <Object>   -Pool <String>   [ -Connection <String> ]   [ -PipelineVariable <String> ]

DESCRIPTION

Enables Continuous Data Protection (CDP) for a virtual disk. This operation can also be performed on a virtual disk group. When enabled, data changes are saved in a history log. If necessary, rollbacks can be created to recover data, see Add-DcsRollback.

NOTE: In order to enable this feature at the group level, all group Members must be eligible for Continuous Data Protection and not already be enabled; otherwise, Members must be enabled individually.

PARAMETERS

-Server<String>

Computer name or ID of the server that will own the history log. The computer name must be unique or the name must be fully qualified.

Required: false

Position: 3

Default value:

Accept pipeline input: false

Accept wildcard characters: false

-VirtualDisk<Object>

VirtualDiskData object, name, or ID that identifies the virtual disk to protect.

Required: true

Position: 1

Default value:

Accept pipeline input: true (ByValue)

Accept wildcard characters: false

-Pool<String>

Name or ID of the disk pool to use as the source of the history log. To resolve by name, the name must be unique to the server group or the server must be specified.

Required: true

Position: 2

Default value:

Accept pipeline input: false

Accept wildcard characters: false

-HistorySize<DataSize>

The maximum size of the history log. Valid values consist of the number followed by the unit of measurement (MiB, GiB, TiB). Decimals may be used. For example, "10GiB", "20.5GiB", and "5000MiB" are valid sizes. The history log size can range from a minimum of 8GiB up to 1024TiB. If not specified, the history log size will be set to the default size which is 5% of the size of the CDP-enabled virtual disk or 8GiB, whichever is larger. Setting the value of this parameter to zero will also set the maximum history log size to the default size.

Required: false

Position: 4

Default value:

Accept pipeline input: false

Accept wildcard characters: false

-Connection<String>

Alias of the connection to the server group. If not specified, the default connection will be used.

Required: false

Position: named

Default value:

Accept pipeline input: false

Accept wildcard characters: false

-PipelineVariable<String>

Required: false

Position: named

Default value:

Accept pipeline input: false

Accept wildcard characters: false

-VirtualDiskGroup<Object>

VirtualDiskGroupData object, name or ID that identifies a virtual disk group. Use this parameter to enable Continuous Data Protection for all eligible virtual disks in the virtual disk group. The VirtualDiskGroupData object can be obtained with Get-DcsVirtualDiskGroup.

Required: true

Position: named

Default value:

Accept pipeline input: false

Accept wildcard characters: false

INPUTS

VirtualDiskData : Object that identifies and describes the virtual disk.

OUTPUTS

VirtualDiskData or VirtualDiskGroupData : Object that identifies and describes the virtual disk or virtual disk group.
