F.2.3 sfcddr(1M) Restores backup data and checks device restoring

[SYNOPSIS]

sfcddr [ -f ] [ if=file ] of=special [ ibs=n ] [ obs=n ]

sfcddr -i [ if=file ] [ ibs=n ]

[DESCRIPTION]

The sfcddr command restores to a disk GFS Shared File System backed up with dd(1M).

Before writing the data to the disk, sfcddr checks the following:

• The specified input file contains GFS Shared File System data or GFS Local File System data.
• The specified disk is the same disk that was backed up.
• The disk is not being mounted.
• All disk partitions are the same size.

If all of the above conditions are not true, the command terminates without restoring the data. Unless an if operand is specified, the standard input is used. An of operand must be specified.

As with dd(1M), input and output block size can be specified in bytes. The alphabetic characters k, b, and w, if specified after a number, indicate 1024 bytes, 512 bytes, and 2 bytes, respectively. In addition, multiplication can be expressed by inserting an x between two numeric values.

After restoring, the sfcddr command reports the number of input/output blocks, the number of complete blocks transferred, and the number of partial blocks transferred.

[OPTIONS]

The following options can be specified:

-f

Does not check to see whether the output device is the same as the device used for backing-up. Use this option if to restore backed-up data to a disk different from which the data was backed up.

-i

Displays the configuration of the partitions of the backed-up file system, the time required to create the file system, and the last mounted directory path. This option does not restore the data.

[OPERANDS]

The following operands can be specified:

if=file

Input file name. The default is the standard input.

of=special

Output device name.

ibs=n

Specify the input block size in n bytes. The default is 512.

obs=n

Specify the output block size in n bytes. The default is 1024k.

[EXIT STATUS]

The termination status is returned as follows:

0 The backed-up data has been restored correctly.

>0 An error has occurred.

[DIAGNOSTICS]

f+p records in(out)

The number of complete (f) and partial (p) blocks that have been read (written)

[NOTES]

• If the backed-up data has been restored to a disk other than the one that the data was backed because the -f option is specified, the partition information must be changed by executing sfcadm(1M).
• Before sfcddr is used, the data may have to be uncompressed with uncompress(1). Uncompressing data will be required if the sfcddr command is used for a backup created with sfcmkbkup(1M) with the -c option specified.

# dd if=/dev/rmt/0 ibs=256k | uncompress -c | sfcddr -i

• Do not backing-up the file system is being added a partition. Use sfcinfo(1M) to confirm whether the partition is being processed, if partition is being processed, execute sfcddr after reexecute sfcadd(1M) to complete process.
