Ask a business owner in Calgary whether their data is backed up, and most will say yes. Ask when they last restored a file, a folder, or a full system from that backup to confirm it works, and the answer is usually a lot less confident. That gap - between having a backup and having a working recovery process - is where most data-loss incidents turn from an inconvenience into a genuine business crisis.
This isn't about a specific piece of software. It's about a handful of decisions that determine whether a backup actually protects the business when something goes wrong: a failed drive, a ransomware attack, an accidental deletion, or a regional outage that takes out power or connectivity for a stretch of time.
Backup and Recovery Are Not the Same Thing
A backup is a copy of data. Recovery is the process of getting a business back to work using that copy - on the right hardware, in the right order, with the right people aware of what to do. A business can have perfect backups and still face days of downtime if nobody has documented how systems depend on each other, who is responsible for what, or how long each step actually takes.
Treating backup as the whole plan is the single most common gap CoreData sees. The copy of the data was never the hard part. Rebuilding a working environment from it, under time pressure, is. This is what real business continuity planning looks like in practice - not a document that sits unread, but a backup and recovery process that's actually been tested under pressure.
What Actually Causes Data Loss
Ransomware gets most of the headlines, and it's a real risk - encrypted files, and increasingly, exfiltrated data used for extortion. But it's rarely the only threat worth planning for. In practice, Calgary businesses lose access to data through:
- Hardware failure - drives, servers, and RAID arrays fail eventually, often without warning.
- Human error - accidental deletion or overwrites are far more common than most people assume, and sync tools can propagate the mistake to every copy.
- Ransomware and other malicious activity - encryption, deletion, or theft of data, sometimes with backups targeted directly.
- Local disruption - power interruptions, connectivity outages, and severe weather events that are a normal part of operating in Alberta.
A backup and recovery plan that only accounts for one of these - usually ransomware, because it's the one people hear about - tends to leave the others unaddressed.
What a Real Backup and Recovery Plan Includes
A dependable plan goes well beyond "we back up to the cloud." It typically includes:
- Retention matched to actual need - not a default setting, but a period based on how far back the business would realistically need to restore from.
- Independent, offsite or immutable copies - so a compromised or deleted primary copy doesn't take the backup down with it.
- A documented recovery order - which systems come back first, who owns each step, and what depends on what.
- Periodic recovery testing - actually restoring data on a schedule, not just confirming the backup job completed.
- Monitoring and alerting - so a failed backup job is caught in hours, not discovered during an actual emergency.
Incremental vs. Differential Backup: What's the Difference?
This is one of the most common points of confusion when businesses set up a backup schedule, and it directly affects both storage cost and how long a restore takes.
Incremental backup copies only what changed since the last backup, whether that was a full backup or another incremental. It's the fastest and smallest backup to run day to day, but a restore has to work through the full backup plus every incremental since, in order - so recovery takes longer and more can go wrong if one link in that chain is corrupted.
Differential backup copies everything that changed since the last full backup. Each differential grows larger than the last until the next full backup resets it, but a restore only needs the full backup plus the single most recent differential - simpler and generally faster to recover from than a long incremental chain.
Neither is universally "better." Incremental suits businesses prioritizing fast nightly backups and larger retention windows; differential suits businesses that weight fast, simple recovery more heavily than backup storage cost. Most dependable backup and recovery plans use a mix - periodic full backups anchoring a schedule of incremental or differential backups in between - matched to the RTO and RPO targets below, not chosen by default.
What Are RTO and RPO?
Two terms are worth understanding before talking to any IT provider about backup, because they turn a vague goal ("don't lose data") into something that can actually be planned and tested:
Recovery Point Objective (RPO) is how much recent work the business can afford to lose - measured in time. An RPO of four hours means, at worst, the last four hours of activity before an incident might not be recoverable.
Recovery Time Objective (RTO) is how long the business can operate without a given system before the outage becomes serious - a few hours for some systems, and potentially longer for others that aren't immediately critical.
These numbers should come from the business, not from whatever a backup tool defaults to. Once they're set, the right question is simple: has this actually been tested against them?
Mistakes That Create a False Sense of Security
- Assuming cloud file sync is a backup. Tools like shared drives keep files available across devices, but a corrupted or deleted file often syncs everywhere. That's not protection against loss - it's the opposite.
- Backing up to a single location. If the backup lives on the same network, or even the same building, as the data it protects, a single event can take out both.
- Never testing a restore. A backup job that reports "success" every night for two years can still fail the one time it's needed, for reasons that only show up during an actual restore.
- No documented plan for people, not just systems. Recovery involves decisions - who declares an incident, who has access to credentials, who talks to customers. Without that written down, technical recovery can be fast and the business can still be stalled.
Where to Start
Businesses don't need to solve every gap at once. A practical starting point is a short review: what's currently backed up, where those backups live, how old the retention settings are, and whether a restore has ever actually been tested. That review usually surfaces the one or two gaps worth fixing first, rather than a long list that never gets tackled.
CoreData designs backup, immutable storage, and disaster recovery around what a business actually needs to keep running, then tests recovery on a schedule so the plan is proven before it's needed for real. That work sits alongside endpoint protection, monitoring, and vulnerability assessment as part of a layered approach to cybersecurity and business continuity, and it's typically delivered as part of ongoing managed IT support rather than a one-time project.
