NFS server

For a backup by NFS Server:

• specify a location only

• a location is in the form server:/dir1/dir2

• a password is not required

SMB server

For a backup by SMB Server (Windows File Sharing):

• specify a location (ﬁleserver and directory), user name and password

• a location is in the form

\\server\share\dir1\dir2

All scheduled backups

For All Scheduled backups, ensure that the target location is available and has

enough disk space to hold the backup archive. Failure to do this may result in

zero-length or truncated archives.

Restore

There are two ways to restore a data set to the Qube 3: use the backup history or

restore the data set manually.

When a backup runs, it creates a new directory in the location speciﬁed in the

Method of Backup section of the Add Scheduled Backup table; see “Creating a

backup” on page 175. The directory name is the time at which the backup was

started and has the form: Year Month Day Hour Minute Second. For example, the

directory name “20000921174533” indicates that the backup was run at 17:45:33

on September 21, 2000.

Restoring with the backup history

If your system failed and you have cleansed your system with the Cobalt

OS Restore CD, your backup history is not available. To retrieve your history ﬁle,

you must transfer the most recent history ﬁle of one of your data sets to the

Qube 3. This is a separate ﬁle within a data set and it always includes the backup

data set with which it was associated. The directory names created by the

backups can be used to determine the most recent backup.

To retrieve a history ﬁle, create the directory /home/users/admin/.cbackup/

and load the history ﬁle in the new directory. This ﬁle must be named history. You

can use any method to transfer the ﬁle there.
