Abstract: One or more techniques and/or computing devices are provided for implementing resynchronization operations. For example, a disaster recovery relationship may be established between a source storage volume, hosted by a source storage node, and a destination storage volume hosted by a destination storage node, such that data is replicated from the source storage volume to the destination storage volume for disaster recovery purposes. If the disaster recovery relationship breaks, then new compliance data, locked down into a write once read many state, may be created at the destination storage volume. A resynchronization operation may be performed to reestablish the disaster recovery relationship, while preserving the new compliance data so that a compliance policy is not violated. For example, cloned storage volumes, copying compliance data to source storage volumes before resynchronization, and/or moving compliance data to local volumes may be used to implement resynchronization operations while preserving compliance data.

Abstract: One or more techniques and/or computing devices are provided for data object retention. For example, a data retention policy may specify that files of a volume are to be locked down for a lockdown retention period (e.g., locked into a read only state for 4 months) when such files are not changed within an auto commit time period (e.g., files not changed within 13 hours). Waiting for a data scanner to evaluate files for lockdown may result in files violating the data retention policy until the data scanner evaluates such files. Accordingly, a file may be considered to be in the locked down state (e.g., instantaneous lockdown), such that commands to modify or delete the file are blocked, based upon a difference between a current time of an internal compliance clock and a current value of a data object change field exceeding the auto commit time period.
Abstract translation: 为数据对象保留提供一个或多个技术和/或计算设备。 例如，当这样的文件在自动提交时间段内没有改变时，数据保留策略可以指定卷的文件被锁定以锁定保留期（例如，锁定到只读状态4个月） 例如，文件在13小时内未更改）。 等待数据扫描程序评估文件进行锁定可能会导致文件违反数据保留策略，直到数据扫描程序评估此类文件。 因此，可以将文件视为处于锁定状态（例如，即时锁定），从而基于内部合规时钟的当前时间与当前值之间的差异来阻止修改或删除文件的命令 的数据对象改变字段超过自动提交时间段。

Abstract: Systems and methods are disclosed for implementing an event based retention schedule for a read only file. When a regular file is to be converted to an event based retention read only file, an “event-retain” property may be enabled on the file allowing the feature to be implemented. Then, that file may have its permissions changed to read only. This will allow the file to be changed to a read only file without using a default retention time. Then, once the event is triggered, the retention time may be set so the file can be scheduled for automatic deletion.
