Data restore system

A data restore system, comprising:

• a memory storing one or more processor-executable routines;
• and
• a processor communicatively coupled to the memory, the processor configured to execute the one or more processor-executable routines to:
• receive a restore trigger to initiate restore operation for selected data from a backup data storage;
• access metadata information for the selected data;
• concurrently receive urls for accessing data blocks for the selected data;
• use the urls to concurrently download data blocks corresponding to the selected data;
• provide the metadata information and the downloaded data blocks to a controller to sort blocks based on files they belong to;
• store the downloaded restored data to a target data storage;
• track real-time progress of the restore operation from the backup storage to the target data storage;
• fetch a page of file path information, file properties, and block map information corresponding to files being restored;
• prepare in-memory entries of a Nextpage token used to fetch the page along with files and blocks to be in-flight;
• concurrently fetch download uniform resource locators (urls) for each blockID of the file data blocks;
• concurrently download blocks from the object storage using the downloaded urls;
• and
• write the downloaded blocks to the target data storage.

A data restore method, comprising:

• receiving a restore trigger to initiate restore operation for selected data from a backup data storage;
• accessing metadata information for the selected data;
• concurrently receive uniform resource locations (urls) for accessing data blocks for the selected data;
• concurrently downloading data blocks corresponding to the selected data;
• concurrently providing the metadata information and the data blocks to a controller to sort the data blocks based on files they belong to;
• storing the downloaded restored data to a target data storage;
• tracking real-time progress of the restore operation from the backup data storage to the target data storage using a checkpointing module;
• fetch a page of file path information, file properties, and block map information corresponding to files being restored;
• prepare in-memory entries of a Nextpage token used to fetch the page along with files and blocks to be in-flight;
• concurrently fetch download uniform resource locators (urls) for each blockID of the file data blocks;
• concurrently download blocks from the object storage using the downloaded urls;
• and
• write the downloaded blocks to the target data storage.
