Microsoft Azure

ImageMaster supports Microsoft Azure storage, which requires configuration via the dialog shown below:

Figure 84: Archives – Azure archive properties

See the table below for Azure parameter descriptions.

Parameter

Mandatory

Description

Endpoint Specification

Yes

The endpoint specification for Azure storage BLOB access

Examples:

  • DefaultEndpointsProtocol=http

Yes

The account name for Azure access

Container Name

Yes

The container will be created if it does not exist.

Blocksize (in kB)

Yes

The block size for writing blob blocks

Maximum size is 4 MB (4096 kB) per block. The block size defines the maximal size of a blob (max= blob block size * 50000) = 200 GB). During the archiving of one blob, the size for a block is reserved in the RAM.

Example: If you specify a blob block size of 65 kB, you are able to archive files with a maximal size of 3 GB.

Connection Timeout

The timeout for a connection for writing blocks (in seconds)

The recommended value is 100 seconds.
