Inactive Store

The contents of the Inactive Store are data files containing mails. These files are typically data files such as EML in ZIP, PST, MBOX, or MAILDIR.  

When to use the Vaultastic Inactive Store

Case 1: Upload data files to a Cloud Store

If your organization has Legacy Data in PST/EML or other data formats and are looking for a low-cost option to save these files on the Cloud, then the Vaultastic Inactive Store is a good option.

Case 2: You want to reduce the size of mailboxes on the primary store but do not want to make the email data searchable

Suppose you are looking to reduce the mailboxes' size on the primary mail server but have not enabled live mail archiving to Vaultastic Active Store. In that case, you can use LegacyFlo to upload data directly from the mailboxes on the primary mail server to the Inactive Store. 

Case 3: You are looking at reducing the size of Vaults on the Active Store

You have enabled live mail archiving from your mail server to the vaults on the Active Store and now are looking at reducing the Active Storage usage without deleting the data. In this case, you can move data from the Active Store to the Inactive Store using LegacyFlo.

Methods for searching through data files on Vaultastic Inactive Store

To search for mail in the data files on the Inactive Store, use the following steps

  1. Identify the data file using the file name. Filenames on the Inactive Store should have the user id and the period
  2. For data uploaded to the Inactive Store using LegacyFlo jobs which move data from Active to Inactive or using jobs which migrate data from IMAP mail boxes, a metadata file associated with the data file is also created on the Inactive Store (these files may not be present for data files created prior to Aug 2021). The metadata files have the same name as the associated data files and have the .csv extension. These CSV files list all the mail in the data file and have the following information: date, sender, recipients and subject. You can download and go through the contents of this file to check if the data you are looking for is present in the data file.
  3. If you have identified the data file within which to search for, then there are multiple options to complete the search and extract the required mails:
    • Method 1: Download the data file to your desktop and import it to a email client such as Thunderbird / Outlook or any other software to search through it.
    • Method 2: You can create a temporary vault on the Active Store and move the contents of the file to that vault and use the eDiscovery app to search through the data
    • Method 3: You can use the LegacyFlo jobs of EML-EXTRACT or PST-EXTRACT to extract the required mails into a EML ZIP file on the Inactive Store. This file will have only the results and can be easily downloaded.
    • NOTE: If it is difficult to identify the data files, then the best way would be to use the LegacyFlo jobs of EML-EXTRACT or  PST-EXTRACT (Method 3) to search for and extract the required mails into a EML ZIP file on the Inactive Store.
  4. The following table will give the factors determining the search time for the different methods
