Data Retention For Google Apps
Google Vault lets you retain, archive, search, and export your organization’s Email and Chat messages for purposes related to ediscovery and compliance. However, Google Vault only covers Mail and Drive - missing critical data from both Contacts and Calendar.
Vault is not a solution for backup. Here’s why: Vault doesn’t create a secondary copy of your data independent of Google—so you have a single point of failure. In addition, because Google Vault is designed for archiving rather than restoring data, when restoring everything must be rebuilt manually—dramatically increasing restore time and effort. That’s why it’s so important to pair a backup solution like Backupify with Google Vault.
