An example method includes receiving, at a server, a request for a list of a first group of index records that correspond to stored data, creating a data streaming session with a client, reading an index file and obtaining a list of the first group of index records from the index file, populating a content cache with a signature that corresponds to the first group of index records, creating a sliding window and populating it with the signature and a pointer to a next group of index records, populating an attribute cache with data streaming session information and the sliding window, creating a continuation token which, when received by the server from the client, indicates to the server that the list of the first group of index records has been received by the client.

Method and approach for pagination over data stream with sliding window

Maintenance management on backup storage systems. Specifically, the disclosed method and system derive backup storage system load from a collection of profiled load factoring features. The backup storage system load may subsequently drive whether maintenance operations may be deferred to projected non-peak load times or, alternatively, may be permitted to proceed.

Maintenance management on backup storage systems

A method for managing virtual machines includes selecting a virtual machine (VM) on a recoverable deleted VMs List, and initiating recovery of the VM on the production host.

System and method for auto recovery of deleted virtual machines identified through comparison of virtual machine management application snapshots and having corresponding backups at a storage device

An example non-transitory storage medium stores computer-executable instructions for execution by one or more hardware processors to perform operations including: receiving at a server a request for a list of a first group of index records that correspond to stored data; creating a data streaming session with a client; reading an index file and obtaining a list of the first group of index records from the index file; populating a content cache with a signature that corresponds to the first group of index records; creating a sliding window and populating it with the signature and a pointer to a next group of index records; populating an attribute cache with data streaming session information and the sliding window; creating a continuation token which, when received by the server from the client, indicates to the server that the list of the first group of index records has been received by the client.

This disclosure relates to a method, article of manufacture, and apparatus for scanning data. In some embodiments, this includes examining attributes of a first directory, wherein the attributes include at least one from a group comprising a next tentative scan date, a modified time, and a dirty indicator, determining if the dirty indicator has been set, if the dirty has been set, scanning files in the first directory, if the dirty indicator has not been set, determining if the first directory has been modified, if the first directory has not been modified, determining if the next tentative scan date equals to a system date, if the next tentative scan date equals to the system date, scanning the files, if the next tentative scan date does not equal to the system date, examining attributes of a second directory, and if the first directory has been modified, scanning the files.

Incremental scan

In one example, a method includes creating a password having 'n' characters that each constitute a byte, placing the characters of the password in a first buffer, generating a random number corresponding to the password, using the random number to map a character in the first buffer to a respective random character present in a second buffer, copying the random character to a third buffer, and removing the mapped character from the first buffer. The mapping, copying, and removing processes are repeated for each character in the first buffer so that the first buffer empties and an 'xth' random string of &#x2018;n&#x2019; length is generated in the third buffer, the &#x2018;xth&#x2019; random string comprising the random characters to which respective characters from the first buffer were mapped. Finally, the &#x2018;xth&#x2019; random string is placed in a fourth buffer and constitutes at least a portion of an encryption key.
