Your Bookkeeper, Not Your IT Vendor, Is the One Who Finds Out Whether the Backup Worked

A backup that has never been restored is a subscription, not a copy. Most households and small businesses buy the subscription, watch the status light stay green for three years, and never learn whether the file that comes back opens in the program that made it. The test is not technical for most people. It is clerical, and the person qualified to run it is usually not the person who sold you the service. That distinction decides whether you find out on a quiet Tuesday or during the week you can least afford it.

The person who finds out whether the restore worked

An IT vendor can prove that bytes came back. Only the person who keeps your books can prove that the right bytes came back, in a form the accounting software will open, with the payroll history attached and the vendor ledger intact. That is the party in the transaction most people overlook: the bookkeeper, the outside payroll processor, the tax preparer who will be asked in a bad month to reconstruct two closed years. Hand one of them a restored copy, ask them to reconcile a single month from it, and you have an answer worth something.

Do it on a schedule you set rather than on the schedule an incident sets. A restore test costs a billable hour or two of bookkeeping time, and that hour is an ordinary business expense in the year you pay it, deductible on the same line as the rest of the bookkeeping fee. Nobody has ever regretted that hour. The households that skip it are usually the ones who assumed the green light and the working file were the same fact, which they are not.

The copy you bought and the company holding it

Read the contract for the name of the entity that physically holds the data, because it is frequently not the name on your invoice. Managed service providers resell storage. Backup applications resell a cloud platform underneath. That third party has its own retention window, its own deletion policy on nonpayment, and its own notice period, and none of those obligations run to you directly. Ask your vendor, in writing, which company holds the copy, how long the copy survives a lapsed payment, and how long a full restore is expected to take.

Get the answer by email and keep it. It costs nothing, it settles an argument later, and it tells you whether the retention window is long enough to cover the period the IRS can still ask about. Retention measured in thirty days protects you from a hard drive failure. It does not protect you from an error made in March and discovered in November, which is the more common shape of the problem.

Which part of the spend comes off this year

Cloud backup billed monthly or annually is a straightforward operating expense, deducted in the year paid on a cash basis, allocated between business and personal use if the same account covers family photographs and client files. Hardware behaves differently. A network drive or a stack of rotating external disks is a purchase of property, and depending on cost and your elections it may be expensed immediately under the de minimis safe harbor, expensed under Section 179, or depreciated. The choice is made on the return, not at the register, and it is worth asking your preparer before December rather than after.

Emergency data recovery, the four-figure invoice from a lab that opens a failed drive in a clean room, is deductible when the data is business data. Personal recovery is not, and the casualty loss rules that once caught some of this were narrowed for individuals. Allocation is the whole game when one device holds both. Write the allocation down at the time, with the basis for it, because reconstructing a reasonable percentage four years later from memory is exactly the exercise an examiner is entitled to be skeptical about.

What has to survive in the file

Three things need to outlive the equipment: the invoices, the allocation worksheet, and the records themselves. The IRS is responsible for the rules on electronic recordkeeping, and its expectation is that stored records remain legible and retrievable for as long as they are material to a return, which for most filers means the full period of limitations rather than the current year. A backup is where those records live. If it cannot be restored into readable form, the records do not exist for this purpose, whatever the storage receipt says.

Keep the restore test itself in the file. A dated note saying who ran it, which month was reconciled, and what came back is cheap to write and hard to reproduce afterward. It also documents business purpose for the spend, which is the ordinary question about any technology invoice that also has a household use.

Set the test before the renewal date, so that a failure gives you a decision rather than a bill you have already paid. Ask the bookkeeper first, the vendor second.
