CrashPlan for Small Business uses two separate methods to determine which files are within your file selection.
- Your operating system’s real-time file watcher
- CrashPlan’s on-demand scan, the File Verification Scan.
Your operating system real-time file watcher service will be running and automatically reporting file selection changes to CrashPlan, which CrashPlan will then append to the backup ‘to do’ list for analysis and upload, once the next backup interval begins.
The File Verification Scan will run, by default, daily at 3:00 AM. If the computer is powered off, asleep or offline during this time, the scan will be delayed until CrashPlan is able to start and connect once again. The File Verification Scan schedule can be configured within the CrashPlan for Small Business Administration console.
You may want to view past scan completion times to get an idea of how long they have taken to complete. This information can be viewed by selecting Tools > History on Windows or Window > History on Mac.
