BackupChain software licenses are perpetual. They come with a one or two year update subscription. During that time you receive free upgrades and technical support. Beyond that time frame the software will continue to function; however, you will no longer receive software updates.
Our optional Cloud Backup Plans, however, have monthly and yearly options and need to be renewed. Cloud backup is an option you may add to an existing software license to send your backups to our secure data center.
