Abstract
A computer-implemented method according to one embodiment includes identifying abnormal data modification characteristics at a first system, determining time data associated with the abnormal data modification characteristics, and adjusting an instance of backup log data stored at a second system, utilizing an identification of the abnormal data modification characteristics and the time data associated with the abnormal data modification characteristics.

A computer-implemented method, comprising:
- identifying abnormal data modification characteristics at a first system;
- determining time data associated with the abnormal data modification characteristics;
- and
- in response to identifying an instance of backup log data within a backup index stored at a second system that has an associated time and date that precedes the time data associated with the abnormal data modification characteristics, adding a freeze retention time to the instance of backup log data within the backup index, where:
- the instance of backup log data includes a record describing backup data retrieved from the first system and stored in storage of the second system, and a pointer to the backup data at the second system,
- the instance of backup log data is stored in the backup index, where the backup index is separate from the storage of the second system where the backup data is stored, and
- the freeze retention time indicates a time period during which the instance of backup log data is to be kept within the backup index and the backup data is to be maintained within the second system.
A computer program product comprising one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media, the program instructions comprising instructions configured to cause one or more processors to perform a method comprising:
- identifying abnormal data modification characteristics stored at a first system, utilizing the one or more processors;
- determining time data associated with the abnormal data modification characteristics, utilizing the one or more processors;
- and
- in response to identifying, utilizing the one or more processors, an instance of backup log data within a backup index stored at a second system that has an associated time and date that precedes the time data associated with the abnormal data modification characteristics, adding, utilizing the processor, a freeze retention time to the instance of backup log data within the backup index, where:
- the instance of backup log data includes a record describing backup data retrieved from the first system and stored in storage of the second system, and a pointer to the backup data at the second system,
- the instance of backup log data is stored in the backup index, where the backup index is separate from the storage of the second system where the backup data is stored, and
- the freeze retention time indicates a time period during which the instance of backup log data is to be kept within the backup index and the backup data is to be maintained within the second system.
A system, comprising:
- a processor;
- and
- logic integrated with the processor, executable by the processor, or integrated with and executable by the processor, the logic being configured to:
- identify abnormal data modification characteristics stored at a first system;
- determine time data associated with the abnormal data modification characteristics;
- and
- in response to identifying an instance of backup log data within a backup index stored at a second system that has an associated time and date that precedes the time data associated with the abnormal data modification characteristics, add a freeze retention time to the instance of backup log data within the backup index, where:
- the instance of backup log data includes a record describing backup data retrieved from the first system and stored in storage of the second system, and a pointer to the backup data at the second system,
- the instance of backup log data is stored in the backup index, where the backup index is separate from the storage of the second system where the backup data is stored, and
- the freeze retention time indicates a time period during which the instance of backup log data is to be kept within the backup index and the backup data is to be maintained within the second system.
