Abstract
A calculated factoring ratio is determined as a weighted ratio of current nominal data to physical data based on at least one storage capacity threshold and a used storage space currently physically consumed by one of backup and replication data. A maximal nominal estimated space in the computing storage environment is calculated. A remaining space, defined as the maximal nominal estimated space minus a current nominal space in the computing storage environment, is calculated.
Claims20
A method for space reservation in a deduplication system by a processor, comprising:
- determining a calculated factoring ratio as a weighted ratio of current nominal data to physical data based on at least one storage capacity threshold and a used storage space currently physically consumed by one of backup and replication data;
- calculating a maximal nominal estimated space in the computing storage environment;
- and
- calculating a remaining space.
A method for space reservation in a deduplication system by a processor, comprising:
- calculating a maximal nominal estimated space in the computing storage environment;
- calculating a remaining space;
- and
- accepting and storing data replication operations in the computing storage environment if the remaining space is one of equal and less than a user-configured reservation space for backup operations.
