Abstract: Systems and methods for managing the storage of recordings in a recording device in which the recordings were requested by several users are provided. Each user may be assigned a storage space limit defining the amount of storage space each user is entitled to use. In some embodiments, the storage space limit may be flexibly increased to take advantage of extra space available from other users. The system may intelligently borrow space from other users to limit the risk that a requested recording is canceled due to unavailable storage resources. In some embodiments, the system may jointly allocate a recording to several users who commonly requested a recording. The system may also set aside space in the recording device that is saved exclusively for a particular user. In some embodiments, the recording device may allocate the storage resources based on the usage of the recordings.
