    摘要： Provided are a method, system, and article of manufacture for determining whether to use a repository to store data updated during a resynchronization. Writes to a primary storage are transferred to a secondary storage. A logical copy of the secondary storage as of a point-in-time is established. Writes to the secondary storage in the logical copy received from the primary storage during a logical copy duration after the point-in-time are stored in a repository that comprises less storage space than the secondary storage in the logical copy. The transferring of writes to the secondary storage is suspended. During the suspension writes to the primary storage are indicated in an out-of-synch data structure. A determination is made as to as to whether available storage space in the repository is sufficient to store writes transferred from the secondary storage while transferring the writes from the out-of-synch data structure in response to ending the suspension of the transferring of writes from the primary to the secondary storages. The repository is used to store data in the secondary storage as of the point-in-time that is to be updated by writes transferred from the primary storage following the ending of the suspension in response to determining that the available storage space in the repository is sufficient to store writes transferred from the secondary storage while transferring the writes indicated in the out-of-synch data structure.

    摘要： Provided are techniques for transmitting blocks of data. It is determined whether any high priority out of sync (HPOOS) indicator is set to indicate that a number of modified segments associated with a block of data are less than or equal to a modified segments threshold. In response to determining that at least one high priority out of sync indicator is set, one or more sub-blocks of data in the modified segments associated with the block of data and with one set high priority out of sync indicator are transferred.
