I've just added a new SATA 4TB internal HDD to my W7 Ultimate box. It's not yet initialized or formatted.
The plan is to create several new partitions on the HDD; a couple for storage plus one dedicated to a Macrium system backup.
How big should the backup partition be? My W7 OS occupies about 135GB of a 250GB Samsung 970 EVO NVME, but I'll likely do incremental or differential backups from time to time, so I guess I'll need enough room for those.
So, a 250GB partition for system backups? Or larger?
