1. Data Retention

The "Data Retention" is an EVSS feature about archiving and storing policies for some historical data.

figure 1. Menu access to the Data Retention

You can access the functions of "Data Retention" using the menu entries shown in figure 1. Menu access to the Data Retention under the "SERVER CONFIGURATION" voice.

The first one is used to configure the Retention features, the latter for retrieving the information stored on the hard disk of PrivateServer.

1.1. Setup of Data Retention

You can configure a retention policy for some important historical data managed by the appliance.

 

figure 2. Data Retention Policy list

 

In figure 2. Data Retention Policy list is shown the list of the available historical data stored. The number of periods configured are kept in internal database. Older data are periodically deleted from internal database and moved out to local file system as a compressed archive that could be later downloaded, archived elsewhere and deleted. 

 

The data involved in the process are deleted from internal database and exported on local file system for archival.

 

 

If you need to understand the data stored in each Data Type, please refer to the logging section of the present manual.

 

 

figure 3. Data Retention Policy editor

Each log entry listed in figure 2. Data Retention Policy list has an editor form as the one shown in figure 3. Data Retention Policy editor. Using the mentioned form you can:

  • enable the Data Retention(Enabled checkbox)
  • select the period to be kept on-line (Period Duration)
  • choose how many archives you want to keep online (Period/s Online)

 

A Privacy option can be setup in order to avoid any Call Record in the appliance. If you set the CDR Period to '0' (zero) then no more CDR logging will be performed for any DIRECT call (calls between two users).

 

2. Retrieve the Data Archives

As said in the previous paragraph (4.0.3.2), there are two left menu entries to manage the Data Retention feature (see figure 1. Menu access to the Data Retention). If you want to access to the stored archives just press the "Archived Data" link.

 

figure 4. Data Archive List

The "Data Archive List" is shown in the page body (see figure 4. Data Archive List). Each archive row shows its Name, its Creation Timestamp and its Size (all the columns are pretty self explaining).

The last two columns shows two icons: the first one is for downloading the archive, the second one is for deleting it.

It's possible to download the archive also by clicking on its name

2.1. Data Archives and Secure Messaging

No content or message body is saved in data retention for Secure Messaging. You can just download a CSV view of Secure Message transport data, such as sender, recipient, acceptance date, delivery status.

3. Delete Data Archives

If you choose to delete the archive, press the last column icon.

figure 5. The confirmation pop-up window

A confirmation is requested (see figure 5. The confirmation pop-up window). If you approve the action then the archive is removed from both the list and the hard disk of the appliance.

Point of no return action!

Please be aware that this action isn't undoable! Once confirmed the deletion, the archive is lost forever!

4. System's logs

In addition to historical data collected in internal database, the two main PrivateServer's components can log debug information in log files.

They main components are:

  • Secure Voip Engine
  • Web Console

Both of them use default system locations (specifically directory /var/log) to store their logs. PrivateServer saves only the last week of these files and rotates them on a daily base. Rotate operation implies both deletion for files oder than one week and archiving in .zip format for the most recent ones. All the log files are labelled by timestamp of the rotation.
