5 Backing Up the iNEWS System
70
A verification request appears:
Do you really want to create a new archive? (n/y)
If there is nothing on the tape that you want to save, type y to continue. A message
similar to the following will appear:
Starting track(1), block(0)
47 stories dumped
Ending track(1), block(34)
n
When you back up a queue, dbdump ignores the queue’s skip flag, so you can use it to back
up a queue or directory that has its skip flag enabled. You can also use this process to save a
queue or directory to tape before removing it from the database. For instance, if you want to
restore database space by removing a queue with material no longer used, use dbdump to
backup the queue first. Then, if you need it later, you can retrieve it from the tape.
t If you have previous backups on the tape, append the next backup to the tape with:
dbdump a -n <queue or directory name>
You can append additional backups to that tape until you use up all space on the
tape. Continuing with the previous example, the next day you would insert the same
tape, make sure its write protect is off, and then type
dbdump a to append that day’s
scripts to the tape:
For instance, after making the first backup of SCRIPTS.2010.FEB shown in the
previous example, back up SCRIPTS.2010.MAR the following month by inserting
the same tape and entering the following:
dbdump a -n scripts.2010.mar
n
If you try to use dbdump a with a tape that does not already contain at least one backup, you
get an Empty tape message. If this happens, use dbdump c instead.
3. When the console prompt returns, the backup is done. Remove the tape and set the
write-protect switch on. Date the tape case label.
4. To verify the backup, type:
dbrestore tdv
This list should be short, but it could take time to complete if the tape contains several
weeks’ worth of backups.
