i

Interactive. Runs ufsrestore in an interactive mode. In this mode, you can use a limited set of shell-like commands to browse the contents of the media and select individual files or directories to restore. See "Commands for Interactive Restore" for a list of available commands.

r

Recursive. Restores the entire contents of the media into the current working directory (which should be the top level of the file system). Information used to restore incremental dumps on top of the full dump (for example, restoresymtable) is also included. To completely restore a file system, use this option to restore the full (level 0) dump and each subsequent incremental dump. Although intended for a new file system (one just created with the newfs command), files not on the backup media are preserved.

R

Resume restoring. Prompts for the volume from which to resume restoring and restarts from a checkpoint. You rerun the ufsrestore command with this option after a full restore (r option) is interrupted.

x [filename...]

Extract. Selectively restores the files you specify by the filename argument. filename can be a list of files and directories. All files under a specified directory are restored unless you also use the h option. If you omit filename or enter "." for the root directory, all files on all volumes of the media (or from standard input) are restored. Existing files are overwritten, and warnings are displayed.

t [filename...]

Table of contents. Checks the files specified in the filename argument against the media. For each file, lists the full file name and the inode number (if the file is found) or indicates the file is not on the "volume" (meaning any volume in a multivolume dump). If you do not enter the filename argument, all files on all volumes of the media are listed (without distinguishing on which volume files are located). If you also use the h option, only the directory files specified in filename, not their contents, are checked and listed. The table of contents is read from the first volume of the media, or, if you use the a option, from the specified archive file. This option is mutually exclusive with the x and r options.

a archive-file [filename...]

Takes the dump table of contents from the specified archive-file instead of from the media (first volume). You can use this option in combination with the t, i, or x options to check for the files in the dump without having to mount any media. If you use it with the x and interactive extract options, you are prompted to mount the appropriate volume before extracting the file(s).

b factor

Blocking factor. Number of 512-byte blocks read from tape at a time. By default, ufsrestore tries to figure out the block size that was used in writing the tape.

d

Debug. Turn on debugging messages. 

f backup-file

Backup file. Reads the files from the source indicated by backup-file, instead of from the default device file /dev/rmt/0m. If you use the f option, you must specify a value for backup-file. When backup-file is of the form system:device, ufsrestore reads from the remote device. You can also use the backup-file argument to specify a file on a local or remote disk. If backup-file is `-', the files are read from standard input.

h

Turns off directory expansion. Only the directory file you specify is extracted or listed. 

m

Restores specified files into the current directory on the disk regardless of where they are located in the backup hierarchy and renames them with their inode number. For example, if the current working directory is /files, a file in the backup named ./dready/fcs/test with inode number 42, is restored as /files/42. This option is useful only when you are extracting a few files.

s n

Skips to the nth backup file on the media (first volume). This option is useful when you put more than one backup on a single tape.

v

Verbose. Displays the names and inode numbers of each file as it is restored. 

y

Continues when errors occur reading the media and tries to skip over bad blocks instead of stopping and asking whether to continue. This option tells the command to assume a yes response.
