Backup

Backing Up OpenVMS Systems

Chapter 5

203

Files with multiple directory entries are only backed up once using
the primary path name. The secondary path entries are saved as soft
links. During a restore, these extra path entries will also be restored.

There is no support for an equivalent to BACKUP/IMAGE. To
make a restored copy of an OpenVMS system disk bootable, the
OpenVMS WRITEBOOT utility has to be used to write a boot block
on to the restored disk.

• Files being backed up are always locked regardless of whether the

Lock files during backup (-lock)

option is enabled or disabled.

With the

-lock

option enabled any file opened for write is not backed

up. With the

-lock

option disabled any open file is backed up as well.

• The default device and directory for pre- and post-exec command

procedures is

/omni$root/bin

. To place the command procedure

anywhere else the file specification must contain the device and
directory path in UNIX style format: For
example:

/SYS$MANAGER/DP_SAVE1.COM

• When specifying wildcards for

Skip (-skip)

Only (-only)

filters, use ‘*’ for multiple characters and ‘?’ for single characters.
