SFTP (Secure File Transfer Protocol) server requirements

If you do not have permission to View Storage Targets that are defined in Enterprise Manager, define an SFTP destination during the export process.

Your enterprise SFTP administrator is responsible for provisioning, configuring, and managing the SFTP server used by the export feature. Management of the server includes:

Allocating disk space for exports.
Managing the disk space used by exported media.
Deleting exported media no longer required.

Audio export disk space requirements

The disk space used for exported audio is a function of:

Audio sample rate
Length of time recorded for each interaction
Number of interactions exported
Zip compression factor (approximate 10% reduction, or a factor of 0.90)

You can calculate the disk space required as follows:

((Sample Rate)/8)*60) * (Avg. Interaction time) * (No. Interactions) * 0.90

Assuming a sample rate of 128 Kbps for two streams/channel, an average interaction length of three minutes, and the maximum number of interactions supported for media export by Risk Management (2,000), the approximate disk space required is:

((128)/8)*60) * (3) * (2000) * 0.90 = 5 GB

The calculation includes the space required for the index HTML file and the zip file.

Chat export disk space requirements

The disk space used for exported chat interactions is a function of:

Storage used by chat messages, including all attachments included with the chats
Zip compression factor (approximate 10% reduction, or a factor of 0.90)

You can calculate the disk space required as follows:

Chat storage requirement * 0.90
