PLAN FOR RECOVERY, NOT JUST STORAGE

How much backup capacity will you need?

Start with the data you care about, add future growth, then plan local and off-site recovery copies with room for version history.

Conservative planning. This treats each backup as a full-copy equivalent. Incremental backups, compression and deduplication can reduce real storage use, while long retention can increase it.

This estimates capacity, not backup quality. A useful backup also needs separation, retention, monitoring and a tested restore process. Build the recovery plan.
