backup capacity, retention, copy count, growth and transfer-time calculators
Plan backup capacity before storage runs out
Model retained copies, data growth, backup-window time and storage headroom from your own backup policy.
Tools
Full Copy Capacity
Calculate storage required for multiple full copies.
Open →ToolsCapacity with Growth
Add a growth percentage to current protected data.
Open →ToolsRetention Set Count
Count retained backups from daily and weekly copies.
Open →ToolsIdealized Backup Window
Estimate transfer time from backup size and sustained throughput.
Open →ToolsStorage Headroom
Calculate remaining storage after reserved backup data.
Open →Guides
Separate copy count from retention policy
A backup plan is easier to size when you state how many restore points you keep.
GuidesAdd data growth explicitly
Current data size is only the starting point for a long-lived backup target.
GuidesEstimate a backup window from throughput
Data size divided by sustained throughput gives an idealized transfer duration.
GuidesKeep storage headroom visible
Running a backup target at full capacity makes retention changes difficult.
GuidesCapacity is only one part of backup planning
A backup that fits is not automatically a backup that can be restored effectively.
