The Importance of Email Retention Journaling and Recoverability and why Cloud Solutions Fail
For most of us, email is simply a means of communicating work. Its a glorified, bi-directional to-do list with comments. Emails come in, we read, do and delete. Once the work is done, theres usually no need to find the email again.
Thats all very true except for when something goes wrong and your company gets taken to court. Suddenly then, all those deleted emails are very, very important.
How Email Discovery could work under Litigation
In the event that email cannot be produced, you could be fined or worse, you could lose the ability to defend your company in court.
...and it doesnt stop there, your company might not even be directly involved in the court case but could be dragged in as a third party via a subpoena.
No matter how lawfully YOU run your business, not having adequate email retention is a business risk that you simply cant afford to take.
Why A Restore is Not Enough
From an IT point of view, we dont usually talk about legal things. Were all about Backups and Restores (and recoverability) as if its simply a matter of getting missing data back.The theory, for example being that if a user loses their file today and theyve not worked on it for a couple of weeks, then any backup from the last few weeks is sufficient.
In this case, the intention is simply to recover the lost data.
What were finding though is that recoverability is much more than simple data restoration. What if, instead of simply recovering the data, we had to prove that no changes had occurred in it between the recovered date and the date it was deleted. The only way to do that would be to recover all versions of this (or to have unquestioned data tracking enabled).
Email is very much a dynamic kind of "file". For example, you might be able to recover a mail from July 7 which was deleted on July 20, via the Backup from July 15, but that doesnt mean that someone didnt reply to that message on July 16 and then delete the reply along with the original message on July 20.
Mail Journaling
Theres only one sure way to demonstrate that youve effectively captured all email;
and...
Have auditing facilities in place to protect the mail stores from administrator intervention or unauthorised access and, have a monitoring process watching the store-process to ensure that it doesnt stop.
In our case, weve been using the Veritas solution... but now weve discovered that moving to IBM Verse will prevent us from being able to journal purely internal mail.
Why the Cloud Systems are failing us
In the past, when we had our own mail servers on-site, we could direct outbound SMTP traffic to go via our external archiving partners, our inbound mail could be captured via redirected MX records and our purely internal mail could be captured via Journaling.With the cloud services, attempting to provide a one-size-fits-all solution, these options are not necessarily available to us. In our case, with IBM Verse, weve been able to sort out inbound and outbound mail mail via the traditional means (after a bit of fiddling) but it turns out that theres no way to journal purely internal mail to an external system (so much for open systems).
We have to abandon our archive solution and go for IBMs offering -- except, of course, that we cant really abandon our old solution because we need to keep it going, possibly indefinitely... unless we migrate it elsewhere (See the Chart at the end of this post).
Ive looked at Microsoft and Google and they seem to have the same problems. Their products dont seem to support external journaling any more (or theyre in the process of depreciating them).
Ive also noticed that since were using cloud services, its no longer possible to restore mail (after the trash has been emptied). This too is a feature of the three cloud services I looked at.
One thing is certain - If youre looking to put your email in the cloud you MUST subscribe to the cloud mail retention service from the SAME vendor.... and, the choices you make today could be the choices you continue to pay for well after youve migrated to a competitors system.
Recommended Reading and thinking
The whole Email Retention thing pretty much kicked off in 2002 with the Sarbanes-Oxley Act in the US. Most of the western world now has an equivalent act in place. If youre not up on that, its good reading.The whole Hillary Clinton thing is worth reading too - its a bit wider than simply mail preservation but its a good example of the rules around email in action.
There are lots of free whitepapers around on Email Retention. Just do a google search and click on some of the PDFs that come up.
Thinking more widely, we need to be prepared for the next leap in litigation; At some point, the courts are going to start asking people to produce records of instant messaging, posts and comments on collaboration platforms.
Do your staff leaving processes leave their collaborative data intact and allocated to the original owner? How do you handle "deleted comments"?
How Long do we need to Retain Email?
This excellent chart is from Contural Incs excellent 2007 Whitepaper: How Long Should Email be Saved? It was sponsored by Symantec who have since moved the business to Veritas. The chart shows that different types of emails have different retention times.
