Backup
Backing Up UNIX Systems
Chapter 5 166
NOTE It is recommended to have root permission on mounted NFS filesystems.
When to Use NFS
Backup Use NFS backup in either of the following situations:
• A system to be backed up is not a part of the Data Protector cell.
• You want to back up system platforms that are not supported by Data
Protector.
To back up a filesystem using NFS, follow the procedure described in
“Example of Creating a Backup Specification” on page 155 until you get
to the
Backup Object Summary page of the wizard. Proceed as follows:
1. In the Backup Object Summary page, click Manual Add .
2. Click the UNIX Filesystem button, and then click Next .
3. In the General Selection page, select a client and manually add the
mount point in the Mountpoint text box. See online Help for details.
Backing Up UNIX Disks as Disk Image Objects
What Is a Disk
Image Backup? A disk image backup is a high-speed backup of disks, disk partitions,
or logical volumes without tracking the file and directory structure
stored on these data sources. Data Protector stores the disk image
structure at the character level.
When to Use a
Disk Image
Backup Use a disk image backup in any of the following situations:
• You have lots of small files and a high backup speed is required.
• A full disk backup is needed, for example, for disaster recovery or
before a major software update.
• A direct disk-to-disk connection is not possible and you want to
duplicate a filesystem to another disk. The latter must be identical to
the original disk.
Where to Find
Rawdisk Sections On the HP-UX and Solaris systems, the rawdisk sections are usually
listed in the
/dev/rdsk directory. On HP-UX, raw logical volumes can be
found in /dev/vg . The first letter of the new logical volume must be
r , for instance /dev/vg01/rlvol2 .
