SYNTAX: /etc/volcopy [options] fsname special1 volname1 special2 volname2
fsname - mounted file system name, e.g.: root, u1, usr!
volname1 - the physical volume name, e.g.: rmt, pk3, t0122!
special - the physical device section, e.g.: /dev/rmct, /dev/rdsk1, etc.
special1 and volname1 - are the device and volume from which
the file system is being extracted.
special2 and volname2 - are the target device and volume!
FLAGS:
-a - invokes a verification sequence requiring a positive
operator response instead of the standard 10 second delay
before the copy is made!
-s - (default) invokes the DEL if wrong verification sequence.
Other options are used only with tapes:
-bpidensity bits-per-inch (i.e., 800/1600/6250),
-feetsize size of reel in feet (i.e., 1200/2400),
-reelnum beginning reel number of a restarted copy,
-buf use double buffered I/O.
GO
The command /etc/volcopy is used for file system copying/backup with
label checking. volcopy is generally recommended instead of
backup because volcopy creates mountable backups and provides
label checking. backup provides neither label checking nor is
the backup it produces mountable. volcopy saves a record of
file/system volumes copied in the /etc/log/filesave.log file.
The syntax for usage and the applicable flags are shown above.
Let us assume that we have a simple system as shown above.
The file system/partition on the special device /dev/fd03
is labeled as a and its directories are highlighted.
Enter the command to copy labeled
partition a on special device
/dev/fd03, to the diskette on
device /dev/rfd1 with a mounted
name of b. The diskette partition
is u2.
$PROMPT$
That is correct!
You've got it on the 2nd try.
Good, you understand the concept.
Please type
volcopy u2 /dev/fd03 a /dev/rfd1 b
Please type
volcopy u2 /dev/fd03 a /dev/rfd1 b
You will be helped this time!
$PROMPT$

volcopy u2 /dev/fd03 a /dev/rfd1 b
Please observe a typical result
above!

At the prompt above, please issue a command to copy the
same file system from the same disk onto the magnetic tape
with volume name t2 on the special device /dev/rmt using
density of 6250 bpi.
$PROMPT$
That is correct!
You've got it on the 2nd try.
Good, you understand the concept.
Please type: volcopy -bpi6250 u2 /dev/fd03 a /dev/rmt t2
Please type: volcopy -bpi6250 u2 /dev/fd03 a /dev/rmt t2
You will be helped this time!
$PROMPT$
FORGET2
volcopy -bpi6250 u2 /dev/fd03 a /dev/rmt t2
Please observe a typical result above.
