Devices, Backup Media, the Physical
Having a month's worth of backup tapes in the
computer room does little good for recovering the system in the
event of an earthquake, flood or fire.
Rotate the last night's backup tape off-site as
soon as possible and return the tape used the night before.
Are the servers and tape backup devices
Is the tape backup device correctly connected
to the UPS?
Do you have enough backup media to do a daily
backup, weekly backups, and monthly backups?
Is the backup media on site with backups
secured against theft or misappropriation?
Is there an adequate separation of duties
between those responsible for performing the backups and those
responsible for programming and maintaining the system data?
Where are the tapes stored for offsite
backups, and is there an easy way to retrieve them when they are
required for restoring?
Is there a schedule in place for replacing
the media and are manufacturer’s recommendations being followed
for the maximum amount of time that backup media should be used
Is there a local vendor that could restore a
backup tape if the backup device fails and you are in a situation
where you need to restore the data quickly?
Is there a backup operator?
Tape Life and Cleaning Cartridge
The most common restore problem is dirty read
heads, then dirty write heads and then bad tape.
A method to accomplish tape replacement is to
purchase enough tape to perform a month's worth of backups and then
replace it after two years.
Use only certified data grade tape.
Make sure you also use a cleaning cartridge on
a regular basis.
