in the range, hold down SHIFT , and then click the last tape in the range. To assign the
selected virtual tapes, click Add for the desired physical tape drive.
Finally, choose the desired backup source:
“ All backups ” allows the miSAN-V-Series to create and maintain tape cartridge dupli-
cates of all the virtual tapes assigned to the drive. When a tape cartridge is inserted
into the drive, “All backups” mode will cause the miSAN-V-Series to automatically
duplicate each virtual tape, ejecting the tape cartridge after each successful copy. If
more than one virtual tape awaits copying, each will be copied in order. Since the vir-
tual tapes are write-protected while auto-archiving occurs, the “All backups” mode is
effective for taking a “snapshot” of the current state of the entire miSAN-V-Series vir-
tual tape cache.
“
Most recent backup only
” allows the miSAN-V-Series to create an immediate
backup of only the most recent virtual tape backup. When a tape cartridge is inserted
into the drive, the “Most recent backup” mode will cause the miSAN-V-Series to auto-
matically duplicate only the most recent virtual tape backup, regardless of how long
ago the backup was made. The miSAN-V-Series will not eject the tape after a suc-
cessful copy, so the tape cartridge will be available for duplicating another backup.
Thus, with the “Most recent backup” mode selected, a user is assured a physical copy
will always be made automatically after a backup to virtual tape. If after a successful
copy a user wants to keep the tape cartridge backup, the user must eject the tape,
else it will be overwritten after the next backup to a virtual tape.
Set Date and Time
This item allows you to set the miSAN-V-Series date, time and timezone using the
local information on the client running the Web Control Panel (See Figure 3-17). The
time information is used for setting the “Last modified” attribute for virtual tapes (See
“Virtual Tape Popup Menu” on page 94 ) and giving a valid timestamp to messages on
Note
To keep track of which virtual tapes have been successfully written to
physical tape and which still need copying, use the Web Control Panel.
The “Copies” column on the “Virtual tapes” tab shows the number of
successful copies made.
