In the IT world, few phrases are as misleading as “it’s been working flawlessly for a year.” This statement often acts as a silent guarantee, masking an underlying fragility. That is, until that silence is suddenly broken one day.
A recent situation we encountered with a client reminded me of this truth once again. The story is familiar: a critical backup repository had been running like clockwork for about a year.
The “Working for a Year” Mythology and Reality
Years of field experience have taught me this: “It’s been working for a year” often means “I haven’t tested it for a year” or “we’ve just been lucky for a year.” Especially with business-critical systems like backups, this can lead to major surprises during a disaster.
In our case, we were using an SMB share as an Acronis backup repository. It was simple, practical, and had been performing its duty admirably for a year. Until that day.
Symptoms Appear: An Unexpected Interruption
One day, we started experiencing issues accessing the backup repository through the management console. Initially, we thought it was a temporary glitch, but the problem wasn’t fleeting. When the access interruption lasted for hours, we understood the severity of the situation. The client’s backups couldn’t be taken, and existing backups were inaccessible.
In such situations, the first thought is usually, “What could have changed?” However, problems can sometimes erupt even when nothing seems to have changed. Especially if there’s an integration between a vendor’s cloud-based service and a local resource, determining responsibility can become complex.
The Dance with Vendor Support: The Importance of the Chain of Evidence
Naturally, to resolve the issue, we opened a ticket with the vendor’s MSP support line. These ticket processes can sometimes take much longer than you expect and require patience. Our case was no different; the correspondence continued for several days.
Multiple support engineers and even partner managers became involved in the process. You’ll often receive standard responses like “after reviewing similar cases…” or “please send these logs…”. This is precisely where creating your own chain of evidence becomes vital.
While talking to the support team, we had to prove past behavior, stating things like, “we had been accessing this area without issues since last year; yesterday, we couldn’t access it for two hours.” This was a testament to how well we monitor our systems and how regularly we maintain logs and timelines.
When there was an issue with the integration between the client’s local SMB repository and the vendor’s cloud console, it was initially unclear which side was responsible. This can further prolong the ticket process, as both parties might claim their part is working fine.
The MSP’s Duty: Disaster Recovery Plan and Our Own Responsibility
While the ticket process dragged on for days, the client’s business continuity was at risk. The inability to take backups was unacceptable. Therefore, we had to consider an interim solution or workaround plan as soon as we opened the ticket.
Steps like identifying an alternative storage location and temporarily redirecting backups there, or taking backups to a local destination, are critical in minimizing the negative impact on the client during such interruptions. The ultimate responsibility to the client always lies with the MSP, so being proactive is essential.
SMB-based backup repositories offer practical solutions due to their ease of setup and cost-effectiveness. However, they are also fragile intersection points. Multiple independent factors like authentication, network connectivity, and the correct functioning of the vendor agent need to be right simultaneously. If even one link in this chain breaks, the entire system collapses.
Lessons and Takeaways: Fragile Intersection Points
I can summarize the key lessons learned from this incident as follows:
- “Working for a year” is no guarantee of anything: Especially in setups residing at the intersection of two sides, like a vendor cloud console and a local repository, always be prepared for unexpected issues.
- Build your own chain of evidence: The key to working efficiently with vendor support is the MSP’s own detailed records. Information like timelines, error messages, and “what changed” lists speeds up problem diagnosis and helps in determining responsibility. The support line won’t keep this detail for you.
- Have your interim solution plans ready: Ticket processes can take days. Since the responsibility to the client is yours, an interim solution or workaround plan must be considered when opening a ticket.
- The sensitivity of SMB-based repositories: While SMB-based backup repositories are practical, they are fragile intersection points because authentication, network, and the vendor agent need to work correctly simultaneously. Extra caution should be exercised with such setups, and regular checks should be performed.
Incidents like these remind us that nothing in the world of technology is absolute, and we must remain vigilant. We not only implement solutions to ensure our security and business continuity but also strive to ensure these solutions are always operational.
