Set a Big Upload Alert Without Drowning in False Alarms
The hardest part of upload tracking is not collecting the data — it is the alert. Set it too tight and it cries wolf until everyone ignores it. Set it too loose and the one upload that mattered slips under it. This page tunes the alert the way experienced admins do: from your own baseline, not from a number copied off the internet.

Every office has a different "big". For an accounts office, 50 MB leaving to an unknown destination is remarkable. For a design studio sending print files, it is Tuesday. So the first rule of alert tuning is: there is no correct threshold, there is only your office's normal — and you find it by watching before you alert. The second rule is that an alert is a question with a deadline, not an accusation. Build the alert to ask good questions, and record the answers, and the system gets smarter every week.
One Week of Uploads — Normal Versus Notable
Company cloud backup, nightlyLarge — known and expected
Video call screen sharingSteady medium — working hours only
Client portal delivery (design files)Large — business pattern, approved host
OS and app update trafficMostly downloads, small uploads

Step 1 — Measure a Baseline Week Before Alerting
Turn logging on, alert on nothing, and read a week of upload records like a diary. You are learning the office's metabolism.
List the top upload destinations and the top uploading PCs, with rough volumes
Mark each one: known service, known reason — or unknown. The unknowns, not the sizes, are your real starting list
Note the rhythms: backup windows, month-end peaks, the design team's delivery days. Your threshold must fit around them

Step 2 — Alert on Destination First, Size Second
Size alone is a weak signal because legitimate work is often huge. Destination is the sharper knife: any significant upload to a service the office has never approved deserves a look, whatever its size.
Build the approved destination list from your baseline: company cloud, client portals, official webmail, backup service
Alert rule one: upload above a modest size to a destination not on the list
Alert rule two: upload above a genuinely large size to anywhere at all — the ceiling that catches even approved services being misused

Step 3 — Set the Numbers From Your Own Data
Pick thresholds your baseline justifies: low enough that the events you saw and disliked would have fired, high enough that a normal busy day fires rarely.
A practical shape: the destination rule fires at tens of MB, the anywhere ceiling at several hundred MB to a few GB, depending on your office's work
Add a time dimension if your platform allows it — large uploads outside working hours deserve a lower threshold than the same upload at noon
Write the thresholds and the date you chose them into the policy file. Future you will ask why the number is what it is

Step 4 — Give Every Alert a One-Line Ending
An alert system lives or dies on its outcomes. Each alert ends in exactly one line, written the day it fires.
The endings are boring on purpose: "backup window, expected", "design delivery to client portal, confirmed with sender", "personal sync found, moved to company account, rule explained"
An alert that ends "unknown, still open" twice is a process failure — chase it or change the alert
Review the month's endings before touching the thresholds. Most tuning decisions become obvious from the endings, not from the raw numbers
🔴 The false-alarm trap has a second floor: if your alerts routinely name people in group emails, staff stop reporting real problems to you. Keep alert handling one-to-one and factual — the alert is about a data flow, and it stays that way until evidence says otherwise.
🎥 Watch the Complete Method in the Video
Watch the video for the tracking setup itself, then give it a week of baseline before you switch your version of this alert on.
There is no universal number — it depends on your office's normal work, which is why the baseline week comes first. As a shape: alert at tens of MB to unapproved destinations, and at a much larger ceiling, often hundreds of MB or more, to anywhere. Then tune from your own alert outcomes, not from anyone else's defaults.
Our backup uploads gigabytes every night. Will it swamp the alerts?
Only if you alert on size alone. Put the backup service on the approved destination list and let the destination rule carry the watch; keep the large-size ceiling above the backup's normal volume so a backup behaving normally never fires, and a backup destination receiving ten times normal still can.
How many alerts a week is healthy?
Few enough that each one gets its one-line ending the same day — for most small offices, a handful. If you are closing dozens daily, the alert is measuring normal work: re-baseline, fix the approved list, or raise the thresholds. An ignored alert is worse than none, because it looks like watching.
