Verifying That STORE Files Are Error Free Using VSTORE
Verifying That STORE Files Are Error Free Using VSTORE
After using the STORE program to back up files, you should check to be sure that no errors
occurred during the backup by using VSTORE. VSTORE verifies that the data written to
backup is valid.
The first place to check is the STORE listing. At the end of the listing, STORE prints a
summary of how many files, HFS directories, symbolic links, and MPE directories were
stored. It will also display the number of files that were not stored, and the number of files
that failed to store. The "files not stored" count includes all files that were specified on the
STORE command line, or in an indirect file, that failed to qualify for the backup. Reasons
for this could include:
• File is open for write access when an online backup was performed.
• File does not meet a DATES or FCODE specification
• User did not have appropriate security requirements to store file
The "files failed to store" count indicates a more serious problem during the backup. These
files qualified for the backup, but an error occurred while actually storing the file to the
backup media. The STORE listing should be examined to determine which files failed to
store, and why.
The user interface for the VSTORE command is similar to that for the RESTORE command
which is described in Chapter 11, "Restoring Files." Command syntax for VSTORE is shown
in Appendix B, "Command Syntax."
To verify one or more files on a STORE backup, mount the backup on your backup device.
The write ring should be removed as a precaution.
As with the STORE and RESTORE commands, you may optionally precede the VSTORE
command with a FILE command assigning a file name to the backup drive. If you do not
assign a filename, a default name is used.
For example, to verify the files on a backup, enter:
:FILE T;DEV=TAPE
Now issue a VSTORE command that backreferences the backup file and includes the file or
files you want to verify. For example:
:VSTORE *T;@.@.@
If you have omitted the FILE command, you would enter:
:VSTORE ;@.@.@
In addition to the backup filename and the names of the files to be verified, four
parameters are available: SHOW, ONERR[OR], LOCAL, and DIRECTORY. The following is a
brief description of each of these parameters:
• The SHOW parameter allows you to list the names of each file successfully verified. (If
you do not specify this parameter, the total number of files verified is displayed.)
Additional options used with the SHOW parameter include short and long form
descriptions of files, creation, last access, last modification date, security status, and an
