F.2.20 sfcproxyrestore(1M) Restores a file system at high speed

[SYNOPSIS]

sfcproxyrestore [ -s ] rel_name

[DESCRIPTION]

sfcproxyrestore executes high-speed restoration of the file system by create instant snapshot from the backup destination to the backup source specified by the relationship rel_name. Therefore the backup source can be used immediately after the command is issued. Before sfcproxyrestore is executed, the relationship between the backup source and destination must have been set up with sfcproxyjoin(1M).

When sfcproxyrestore is executed, the following conditions must have been satisfied.

• The file system at the backup source must have been unmounted.
• The file system at the backup destination must have been unmounted.
• Copy processing must not have already been executed at the backup source or destination.
• The backup destination must have been separated from the backup source (must not be in join status).
• The backup source and destination volumes of GDS must not be data invalid (INVALID) status.

After sfcproxyrestore is executed, the backup destination is put in the join status with the backup source. Issue sfcproxybreak(1M) to break the relationship after copy processing is completed so that backup can be executed again. Then later, if necessary, set up the relationship again.

[OPTION]

The following option can be specified:

-s

Synchronization specification. This option waits for the real copy processing to be completed.

[OPERAND]

The following operand can be specified:

rel_name

Specify the relationship of a restoration target by using relationship name rel_name.

[EXAMPLES]

(Example 1)

To restore from the backup destination to the backup source specified with the relationship with the relation ship name backup1_for_volume0001 in the EC operation, and to EC employment is restarted. Execute the following command.

# sfcproxyrestore -s backup1_for_volume0001
# sfcproxyinfo -f backup1_for_volume0001 > /var/tmp/relation_backup
# sfcproxybreak backup1_for_volume0001
# sfcproxyjoin equivalent -r backup1_for_volume0001 -f /var/tmp/relation_backup

(Example 2)

To restore from the backup destination to the backup source specified with the relationship with the relation ship name backup1_for_volume0002 in the OPC operation, and to OPC employment is restarted. Execute the following command.

# sfcproxyrestore -s backup1_for_volume0002
# sfcproxyinfo -f backup1_for_volume0002 > /var/tmp/relation_backup
# sfcproxybreak backup1_for_volume0002
# sfcproxyjoin separate -r backup1_for_volume0002 -f /var/tmp/relation_backup

(Example 3)

To restore from the backup destination to the backup source specified with the relationship with the relation ship name backup1_for_volume0003 in the EC operation with group, and to EC employment is restarted. Execute the following command.

# sfcproxyrestore -s backup1_for_group0003
# sfcproxyinfo -f backup1_for_group0003 > /var/tmp/relation_backup
# sfcproxybreak backup1_for_group0003
Delete all file system of backup destination by sfcadm(1M).
Delete all volume that under backup destination group of GDS by sdxvolume(1M).
# sfcproxyjoin equivalent -r backup1_for_group0003 \
-g /dev/sfdsk/class0003/rdsk/volume0003 -f /var/tmp/relation_backup

[EXIT STATUS]

The following exit values are returned:

0

Successful completion.

>0

An error occurred.

[NOTES]

• A full data copy is executed. Therefore, an I/O load is applied on the backup source and destination.
• Optional product PRIMECLUSTER Global Disk Services Snapshot is required for this function.
