recover 命令

常用示例

说明

recover is an alternative name/symlink for the restore utility used by the dump/restore ext2/3/4 backup system. It reads a backup archive produced by `dump(8)` and writes the selected files back to disk. Interactive mode (`-i`) gives you a tiny shell for browsing the archive: `ls`, `cd`, `pwd`, `add`, `delete`, `extract`, `quit`. On some systems (notably NSR/NetWorker), `recover` refers instead to a very different tool — the client-side restore interface for the Legato/EMC NetWorker backup server. The flags and behavior below describe the dump/restore lineage; for NetWorker, consult `recover(8)` on that system.

参数

-i

Interactive restore: browse the archive and pick files.

-r

Restore an entire filesystem. Run in an empty, freshly created filesystem.

-R

Resume a previously interrupted `-r` restore.

-t

Print the table of contents of the archive.

-x

Extract the named files (or the whole archive if no names given).

-C

Compare archive contents with the filesystem.

-f _file_

Archive file or device (e.g. `/dev/nst0` or `backup.dump`). Use `-` for stdin.

-v

Verbose: print each file as it is processed.

-N

Do everything except actually writing files to disk (dry run).

-y

Do not ask whether to abort on tape errors; always try to continue.

-h

Do not recurse into directory hierarchies when extracting.

-m

Extract by inode number instead of name.

-s _n_

Skip to the _n_th dump file on a multi-file tape.

-b _size_

Block size (in kilobytes) for reads.
