Definitions
- the present invention relates generally to a method and system for processing email during an unplanned outage. More particularly, the present invention provides for the redirection of email during an unplanned outage, notifies users that alternative access is available to said email, and restores messages received during the unplanned outage into the users' original email system to maintain the integrity of the email file.
- email messaging is a mission critical application worthy of inclusion in a business continuity plan. Previously, companies that made this decision had no alternative but to implement expensive and complex systems.
- the solution has been to replicate the company' s entire email system, such as a Microsoft Exchange database, in a remote datacenter on hardware similar to that owned by the company. Because of the complexity of such system, such as Microsoft's Exchange architecture, replication strategies have focused on real-time database replication of disks at the byte level or, alternatively, on transferring offline database backups on a server-by-server basis.
- Incapacitation Due to Virus Similarly, if a virus occurs in a file on the original server, it will be transported to the second server. Server corruption due to viruses can cause email outages for days . 5. Transactional Inconsistency. Because replication solutions typically perform byte-level replication of the disks, they do not provide integrity for the Exchange transaction boundaries. For example, a single transaction on Microsoft Eschange may consist of ten sequential writes to the disk. If the replication software has only replicated eight of those ten at the time of an outage, then the backup will be incomplete, resulting in a corrupt file which may fail to mount.
- the present invention relates generally to a method and system for processing email during an unplanned outage and substantially departs from the conventional concepts and designs of the prior art. More particularly, the present invention comprises the steps of managing users' email; redirecting inbound email messages from a primary server to a secondary server when said primary server is unavailable; notifying said users that the redirection of inbound email messages has been implemented; providing the users with access to the email addresses on a secondary server while the primary server is unavailable; notifying users when the primary server is again available; and incorporating the email messages received while the primary server was unavailable into the software for managing users' email so as to create a complete email history.
- FIG. 1 is a flow diagram of a typical prior art replication process
- FIG. 2 is a diagram showing the preferred method of the present invention for processing email during an unplanned outage
- FIG. 3 is a diagram showing a method for replicating email addresses on a secondary server.
- FIG. 1 is a flow diagram of a typical replication process. Inbound email messages 101 are received and processed on the primary server 102. On a periodic basis, the information on the primary server 102 is replicated on a secondary server 103. The replication process can occur at the byte level, the file level or the disk level.
- the replication system is configured such that only files or disks to which changes have been made are replicated.
- the secondary server is activated.
- the primary server 102 and the secondary server 103 do not act in concert, it is necessary to take the primary server 102 completely offline before activating the secondary server 103.
- FIG. 2 shows a diagram outlining the preferred method for processing email during an unplanned outage.
- inbound email messages 201 are redirected from a primary server 220 to a secondary server 230 when said primary server 220 is unavailable. Users are notified that email messages 201 have been redirected and those users are provided access to their email messages 201 via the secondary server 230. Users are again notified when the primary server 220 is available. Thereafter, the email messages 201 that were received while the primary server 220 was unavailable are synchronized with the preexisting email messages 201 on the primary server 220 to create a continuous email history.
- inbound email messages 201 are sent to a server gateway 210. In a corporate environment, inbound email messages may be sent from customers, vendors, partners, suppliers and the like.
- inbound email messages are routed to an email application 240 residing on the primary server 220.
- a registry of all email addresses residing on the primary server 220 is kept either on the primary server 220 or on the server gateway 210.
- the method of determining the email addresses that reside on the primary server 220 utilizes functionality inherent within the email application 240. In other cases, the method of determining the email addresses that reside on the primary server 220 may be an independent program operating autonomously.
- email addresses that are redundant to the email addresses residing on the primary server 220 are created on the secondary server 230.
- the secondary server 230 can be located remotely from the server gateway 210 and may be connected, for example, through the internet.
- a message will be employed whereby the email addresses on the secondary server 230 will be updated on a periodic basis to replicate the email addresses on the primary server 220.
- This creation of redundant email addresses on the secondary server 230 is continued on an ongoing basis.
- a method is next employed to detect whether email addresses that reside on the primary server 220 are detectable to inbound email messages 201. In some cases, this detection can be as simple as monitoring the email flow for error messages indicating a delivery failure. In other cases, an automated method may be employed which continually monitors a flow of inbound messages 201 to determine whether they are received on the primary server 220 as intended.
- the inbound email messages 201 are redirected from the primary server 220 to the secondary server 230.
- the transition from the primary server 220 to the secondary server 230 can be done automatically to determine that the email addresses on the primary server 220 are not being detected by inbound email messages 201. It is also possible to direct only a portion of the inbound email messages 201 from the primary server 220 to the secondary server 230 in cases where only a portion of the email addresses residing on the primary server 220 are undetectable to inbound email messages 201.
- a decision may be made to transfer all inbound email messages from the primary server 220 to the secondary server 230 even though only a portion of the email addresses on the primary server 220 are undetectable to inbound email messages 201.
- primary server 220 may be prone to additional failure.
- It may also be desirable in those cases where the transition from the primary server 220 to the secondary server 230 is performed manually, to implement a password protection scheme whereby ability to effectuate the transition requires the entering of a password.
- a notification is sent to users alerting them that email messages are available on the secondary server 230.
- the notification method may consist, for example, of the automated delivery of notification messages 250 to an alternate email address for each of the users.
- the aforementioned notification messages 250 can be sent to, for example, cellular telephones, personal digital assistance, pagers and the like.
- inbound email messages 201 are directed to the secondary server 230.
- continual assessment is underway to determine when email addresses, residing the primary server 220, are again detectable to inbound email messages 201.
- This activity may take the form of, for example, periodically pinging the email addresses residing on the primary server 220 and evaluating whether a response is received.
- inbound email messages 201 that had been directed to the secondary server 230 can be redirected back to the primary server 220.
- users can be notified that the primary server 220 is again operational and that their traditional email application 240 is functioning.
- the notification to users can again be in the form of a notification message delivered to each user's alternate email address.
- This functionality permits a gradual transition back to the affected primary server 220.
- redirecting inbound email messages 201 from the primary server 220 to the secondary server 230 can be effectuated in less than two minutes compared to the 30-60 minutes required in traditional replication systems.
- FIG. 3 is a diagram showing a method for replicating email addresses on a secondary server.
- email addresses that reside on a primary server are monitored using a means independent from the email application used to process email messages to create a registry of existing email addresses 301.
- a query 302 is sent to the primary server to determine changes to the registry. More specifically, the query will seek to determine whether email addresses exist in the registry 303, if there are email addresses that do not exist in the registry 304, or whether the email addresses are currently being updated in the registry 305. If the email address exists in the registry 303, then no further action is taken and the system repeats the query on a 302 on a periodic basis.
- the email address is added to the registry 306 and the address is updated on a secondary server 308. Thereafter, additional queries 302 are run on a periodic basis. Finally, if the email address is being updated in the registry 305, that status is noted in the registry 307 and the added queries are run in the future to determine the updated status .
