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) or Only (-only)
filters, use ‘*’ for multiple characters and ‘?’ for single characters.
