Email archiving is the practice of keeping a copy of every sent and received message in a separate, indexed and tamper-resistant repository so it can be retrieved for years for legal, audit or compliance purposes. Unlike backup, which is used to restore mailboxes after data loss, archiving lets an organization prove what was communicated, to whom and when.

Redundant internet link (dual ISP)
Dual ISP failover is the use of a second internet connection, ideally from a different ISP (internet service provider) over a separate physical path, that keeps operations running if the primary connection fails. The firewall or SD-WAN (software-defined wide area network) appliance detects the outage and switches traffic automatically. While both links are up, it can also balance the load between them.
Google Workspace backup
Google Workspace backup is an independent copy of an organization's Gmail messages, Drive files, calendars and contacts, stored outside the Google environment. Under the shared responsibility model, Google keeps the service available, but protecting data against deletion, ransomware or departing staff is the customer's responsibility; the native trash and retention settings have limits.
Point-in-time recovery
Point-in-time recovery (PITR) is the ability to restore a system, database or file to the exact state it was in at a specific moment, for example just before an accidental deletion or a ransomware encryption. It depends on keeping multiple versions or change logs, and the available window is set by the service's retention period.
Ransomware recovery
Ransomware recovery is the process of containing the incident, removing the attacker's access and restoring systems and data to a clean, verified state. It usually includes isolating devices, investigating how the attacker got in, restoring from immutable or isolated backups and confirming no malware remains; paying the ransom does not guarantee the data will be recovered.
Data replication
Data replication is the process of copying data continuously or periodically from one system to another, for example from an office server to a cloud data center, so a ready copy exists if the original fails. Unlike a backup, a replica also mirrors errors and ransomware encryption, so it does not replace a backup with version history.
