Feature Description: Restores (restore) a file or an entire file system (a partition) backed up by a dumping (dump) operation.

Grammar: restore&http://www.aliyun.com/zixun/aggregation/37954.html ">NBSP;" [-ccvy] [B < block size] [-D < file system] [F < backup file] [-S < file number] or restore [-chimvy][-b < chunk size >][-f < backup file >][-s < file number] or restore [-crvy][-b < block size >][-f < backup file >][-s < file number] or restore [-crvy][-b < chunk size >][-d < file system >][-f < backup file >][-s < File number or restore [Chtvy][-b < chunk size >][-d < file system >][-f < backup file >][-s < file number >][file ...] or restore [- Chmvxy][-b < block size >][-d < file system >][-f < backup file >][-s < file number >][file ...]

Supplemental NOTE: The restore instruction operates on the contrary to the dump directive, which can be used to back up files, and the restore operation is to write back these backed up files.

Parameters：
-b< Chunk Size > Set block Size, in bytes.
-C does not check the backup format of the dumping operation, only the backup files used in the old format are allowed to be read.
-C uses contrast mode to compare backed up files against existing files.
-d< File System > allows the user to specify the name of the file system.
-f< backup files > read backup data from specified files for restore operations.
-H only the directory is extracted, excluding all files associated with the directory.
-I uses interactive mode, and the restore instruction asks the user in turn when the restoration operation is performed.
-M unlocks a file or directory that matches the specified inode number instead of using a file name designation.
-R for restore operations.
-R When the file system is fully restored, check where to start.
-s< File Number > You can specify the number of the backup file when the backup data exceeds a volume of tape.
-t specifies the name of the file, and lists the names if the file already exists in the backup file.
-V Displays the instruction execution process.
-X sets the file names and reads them from the specified storage media, restoring them to the file system if the file already exists in the backup file.
-Y does not ask any questions to agree to answer and continue to execute instructions.
