> what is the file size limit

The actual file size limit of the portal is 1GB. SkyTransfer file size limit is ~700MB. Since the encrypted data are Base64 encoded and the Base64 encoding has an overhead of 33%, the encrypted data are correspondingly larger compared to the unencrypted data. This limit will be increased as soon as possible.

> minimal storage period

Files uploaded to Skynet will remain available as long as a portal pins the skyfile (agrees to pay from it). The rule-of-thumb for a minimum time is 3 months, but this will vary from portal to portal and could depend on if you have a user account with the portal. You can pin files yourself by running your own portal, and any portal can pin any file that already exists on the network. https://support.siasky.net/key-concepts/faqs#how-long-does-d...
