Using the dump command

Specifying the dump path

What the dump path does

The dump path specifies one volume, qtree, or subtree to back up. A subtree is a directory in a volume or qtree.

Ways of specifying a dump path

You can specify a dump path in the following ways:

By specifying a single path name
By using a qtree batch file

Specifying a single path name

You can simply specify a volume, qtree, or subtree to back up all the data in it. The volume, qtree, or subtree can be in either of the following locations:

The active file system, for example, /vol/volname/home
A snapshot, for example, /vol/volname/.snapshot/weekly.0/home

To specify a single dump path, complete the following step.

Step	Action
1	Put the path name of the volume, qtree, or subtree that you want to back up at the end of the `dump` command.

Example

The following command contains the dump path /vol/vol0:

Using a qtree batch file

You can back up several qtrees from a volume with the same command by using a qtree batch file. Using a qtree batch file involves creating the batch file, then specifying it as part of the dump command.

Creating a qtree batch file

To create a qtree batch file, complete the following steps.

Step	Action
1	Create a file anywhere in a volume that contains qtrees that you want to back up.
2	Add to the file the name of each qtree that you want to back up, one qtree name to a line. The following rules apply to the batch file: The qtrees must all be in the same volume as the batch file. You can have up to 255 qtree names in the file. There must be no blank lines in the file. Note Leading and trailing spaces are treated as part of the qtree name.

Step

Action

Create a file anywhere in a volume that contains qtrees that you want to back up.

Add to the file the name of each qtree that you want to back up, one qtree name to a line. The following rules apply to the batch file:

The qtrees must all be in the same volume as the batch file.
You can have up to 255 qtree names in the file.
There must be no blank lines in the file.
Note
Leading and trailing spaces are treated as part of the qtree name.

Example

The following misc/files/qtreefile qtree batch file in the /vol/vol0 volume backs up the qtrees /vol/vol0/qtree1, /vol/vol0/qtree2, and /vol/vol0/qtree3:

qtree1

qtree2

qtree3

Specifying a qtree batch file

To specify a qtree batch file, complete the following step.

Step	Action
1	Put the path name of the qtree batch file at the end of the `dump` command.

Example

The following command backs up the qtrees named in the misc/files/qtreefile batch file in the /vol/vol0 volume:
