NetBackup cloud storage server connection properties

All or most of the cloud storage servers use the storage server properties in Table: Storage server cloud connection properties. The following are the prefixes for the currently supported cloud vendors:

  • Amazon: AMZ

  • Amazon GovCloud: AMZGOV

  • Cloudian: CLD

  • Google Nearline: GOOG

  • Hitachi: HT

  • Microsoft Azure: AZR

  • Verizon: VER

Table: Storage server cloud connection properties

Property

Description

METER:DIRECTORY

This read-only field displays the directory in which to store data stream metering information.

Default value: UNIX: /usr/openv/var/global/wmc/cloud or /usr/openv/netbackup/db/cloud (on media server versions 7.7.x to 8.1.2 only)

Windows: install_path\Veritas\NetBackup\var\global\wmc\cloud or install_path\Veritas\NetBackup\db\cloud\ (on media server versions 7.7.x to 8.1.2 only)

METER:INTERVAL

The interval at which NetBackup gathers connection information for reporting purposes.

NetBackup OpsCenter uses the information that is collected to create reports. The value is set in seconds. The default setting is 300 seconds (5 minutes). If you set this value to zero, metering is disabled

To change this property, use the Cloud Settings tab of the Scalable Storage host properties.

See Scalable Storage properties.

Default value: 300

Possible values: 1 to 10000

PREFIX:CURL_CONNECT_TIMEOUT

The amount of time that is allocated for the media server to connect to the cloud storage server. This value is specified in seconds. The default is 300 seconds or five minutes.

This only limits the connection time, not the session time. If the media server cannot connect to the cloud storage server in the specified time, the job fails.

This value cannot be disabled. If an invalid number is entered, the CURL_CONNECT_TIMEOUT returns to the default value of 300.

Default value: 300

Possible values: 1 to 10000

PREFIX:CURL_TIMEOUT

The maximum time in seconds to allow for the completion of a data operation. This value is specified in seconds. If the operation does not complete in the specified time, the operation fails. The default is 900 seconds (15 minutes). To disable this timeout, set the value to 0 (zero).

Default value: 900

Possible values: 1 to 10000

PREFIX:ESFS_HOST

Identifies the host that contains the ESFS cache. The ESFS cache is used by a CloudCatalyst storage server for deduplication to the cloud.

This property is set internally and cannot be changed by the user.

PREFIX:LOG_CURL

Determines if cURL activity is logged. The default is NO which means log activity is disabled.

Default value: NO

Possible values: NO (disabled) and YES (enabled)

PREFIX:READ_BUFFER_SIZE

The size of the buffer to use for read operations. READ_BUFFER_SIZE is specified in bytes.

To enable the use of the buffer, set this value to a non-zero number.

The READ_BUFFER_SIZE determines the size of the data packets that the storage server transmits during each restore job. An increase in the value may increase performance when a large amount of contiguous data is accessed. If insufficient bandwidth exists to transmit the specified amount of data within a few minutes, restore failures may occur due to timeouts. When you calculate the required bandwidth, consider the total load of simultaneous backup jobs and restore jobs on multiple media servers.

See About object size for cloud storage.

PREFIX:USE_SSL

Determines if Secure Sockets Layer encryption is used for the control APIs. The default value is YES, meaning SSL is enabled.

Default value: YES

Possible values: YES or NO

PREFIX:USE_SSL_RW

Determines if Secure Sockets Layer encryption is used for read and write operations. The default value is YES, meaning SSL is enabled.

Default value: YES

Possible values: YES or NO

Provider Suffix: USE_CRL

If SSL is enabled and the CRL option is enabled, each non-self-signed SSL certificate is verified against the CRL.

PREFIX: OBJECT_SIZE

The size of the data object that NetBackup sends to the cloud storage server with an HTTP PUT and GET requests.

Object Size is specified in bytes. You cannot edit the Object Size once you set the value.

PREFIX: WRITE_BUFFER_NUM

This parameter is not applicable for Amazon S3-compatible cloud providers.

This read-only field displays the total number of write buffers that are used by the plug-in. The WRITE_BUFFER_SIZE value defines the size of the buffer. The value is set to 1 and cannot be changed.

Default value: 1

Possible values: 1

PREFIX:WRITE_BUFFER_SIZE

The size of the buffer to use for write operations. WRITE_BUFFER_SIZE is specified in bytes.

To disable the use of the buffer, set this value to 0 (zero).

The WRITE_BUFFER_SIZE value determines the size of the data packs transmitted from the data mover to the storage server during a backup. An increase in the value may increase performance when a large amount of contiguous data is accessed. If insufficient bandwidth exists to transmit the specified amount of data within a few minutes, backup failures may occur due to timeouts. When you calculate the required bandwidth, consider the total load of simultaneous backup jobs and restore jobs on multiple media servers.

See About object size for cloud storage.

HTTP:User-Agent

This is applicable only for Amazon S3-compatible cloud providers.

This property is set internally and cannot be changed by the user.

HTTP:x-amz-server-side-encryption

This is applicable only for the following cloud providers: Amazon S3 and Amazon GovCloud

Use this property to enable the server-side encryption of the data that you need to transfer to the cloud storage.

AES-256 is a server-side encryption standard.

Set this property to NONE to disable the server-side encryption for the cloud provider.

Note:

You should not enable this property, if you have already enabled the media server-side encryption option while configuring cloud storage server using the NetBackup Administration Console.

AMZ:REGION_NAME

This is applicable only for Amazon GLACIER_VAULT storage class.

Displays the region set during configuration of the storage server.

This property is set during configuration of the storage server and cannot be changed by the user.

AMZ:UPLOAD_CLASS

Use this property to specify the retrieval retention period in days.

AMZ:TRANSITION_TO_STANDARD_IA_AFTER

This is applicable only for the LIFECYCLE storage class.

If you have set the UPLOAD_CLASS as STANDARD, the TRANSITION_TO_STANDARD_IA_AFTER must be set to either NONE or in the range 30 to 2147483617.

If you have set the UPLOAD_CLASS as STANDARD_IA, the TRANSITION_TO_STANDARD_IA_AFTER must be set to NONE.

AMZ:TRANSITION_TO_GLACIER_AFTER

This is applicable only for the LIFECYCLE storage class.

If you have set UPLOAD_CLASS as STANDARD, and if TRANSITION_TO_STANDARD_IA_AFTER is set in the range 30 to 2147483617, you must set TRANSITION_TO_GLACIER_AFTER as NONE or in the range 60 to 2147483647. This value includes a minimum stay of 30 days for the data in the STANDARD_IA storage class.

If you have set UPLOAD_CLASS as STANDARD, and if TRANSITION_TO_STANDARD_IA_AFTER is set to NONE, you must set TRANSITION_TO_GLACIER_AFTER in the range 1 to 2147483647.

If you have set UPLOAD_CLASS as STANDARD_IA and if TRANSITION_TO_STANDARD_IA_AFTER is set to NONE, you must set TRANSITION_TO_GLACIER_AFTER in the range 30 to 2147483647.
