Physical Restore

In a physical restore, data is extracted from a level-0 archive. When performing a physical restore, archecker performs the following tasks:

• Reads the schema command file to determine the following:
  • The source tables
  • The destination tables
  • The schema of all tables
  • The dbspace names of where tables are located
  • The specific archive to extract data from
• Scans the archive for pages belonging to the tables being restored
• Processes each row from the data page and determines if the row is complete or partial.

  If the row is a partial row, then archecker determines if the remaining portion of the row has been staged, and if not, it stages the row for later processing.

• For a physical-only restore, applies filters to the row and rejects rows that are not required.
• Inserts the row into the destination table.
