Description
The mkjfsback command is used to perform a backup of one or more filesystems.
The mount point parameter, which is the directory name where each filesystem is
mounted (such as /home), indicates the filesystems to include. You can back up
multiple filesystems by appending each mount point to the end of the command,
separated by spaces.
The backup can be performed to a tape drive, virtual device, or disk image file.
When specifying a disk image file, you can enter the full pathname of the file to
create or overwrite. When doing so, the filename must begin with the prefix “FS”
to indicate the file is a filesystem backup. You can also specify only the backup
directory and a unique ID. When doing so, a filename will be created for you.
Refer to “Backups to Disk Image Files” on page 2-6 for information on the
filename created. If you are creating a file and a file by the same name already
exists, specify the -O option to overwrite the existing file.
The backup can also be performed to a remote device, virtual device, or disk
image file. If Remote Services has been configured on both the local and server
system using the cfgremsvs command, and you have defined a backup device on
the server for use by this system using the cfgremaccess command, then you can
also select a hostname using the -h option. The backup will then be written to the
device or filename on the specified server, provided the server has enabled this
system access to the specified device or directory.
A level 0 backup must be performed before any level 1-9 can be performed. Refer
to “Understanding Incremental Backups” on page 4-1 for additional details on
incremental backups.
