Salesforce Backup Licenses and Renewals.

When you add Salesforce users, you’ll have the flexibility to add more Veeam Backup for Salesforce licenses and co-term your different license purchases to match up with the same subscription cycle. This keeps subscription expiration dates and renewals simple and straightforward.
At the end of the license period, the use of the product as well as support will be turned off. To renew a subscription license, simply purchase another subscription license at the then-current rate.
You can also purchase multi-year subscriptions to lock in the current price.
