A storage contains the data that inSync backs up from user devices. A storage is created on an inSync Storage Node. You can have multiple storage on an inSync Storage Node. However, we recommend that you create the least number of storage on an inSync Storage Node. This helps in the optimal usage of inSync data deduplication and saves space on your storage.
The size of a storage depends on various factors such as the number of users backing up their data on the storage, the average data that the users are backing up, and the type of data that users are backing up.
