I want to setup OwnCloud for sharing a little less than 2 TB of data. I’m wondering right now how I should calculate the disk size, e. g. how much overhead there is. Or stated differently, how much real storage space should I have for 2 TB of data?
I think more important is how often the files change, and how often you delete files. File versioning and the trashbin are based on user quotas, so if you only have 1 user, this should not be a problem, but if you have multiple users with no quotas set, this could become complicated.
Also, bear in mind that file encryption increases the file size by 30%.
