STORE and TurboSTORE/iX Command Options
TurboSTORE/iX 7x24 True-Online Backup Options
To compress data when storing files to backup, use the FILE command, then use the
COMPRESS parameter in your STORE command. For example:
:STORE @.OPERATOR.SYS;*T;COMPRESS=HIGH
WARNING
If you are using a backup device that performs hardware data
compression, COMPRESS=HIGH should NOT be used. Performing
compression twice is redundant, and in some cases can lead to
slower backup performance. The best throughput results occurs
when using no compression or COMPRESS=LOW with hardware
compressing devices.
TurboSTORE/iX 7x24 True-Online Backup Options
In addition to the above options, the following options are available with TurboSTORE/iX
7x24 True-Online Backup:
ONLINE After a short attach period, files can be accessed and modified during
backup.
ONLINE=START ONLINE=END Files can be accessed without interruption throughout the
backup.
LOGVOLSET Allows you to specify what volumeset should be used for online backup log
files.
Store to Disk Instead of writing to a tape or MO device, STORE can write the backup to a
disk file. Refer to Chapter 3, "Preparing Storage Devices," for more
information.
Storing Files Online (ONLINE)
Using TurboSTORE/iX 7x24 True-Online Backup, you can back up files and applications
that need to be available most or all of the time. TurboSTORE 7x24 True-Online Backup
can perform two different types of online backups:
• Using the ONLINE option only:
The first type of online backup requires that all files being store be close for write access
when the backup first starts. This is the type of online backup available on pre-MPE/iX
5.5 systems, when the TurboSTORE/iX II with Online Backup products are used
(product numbers HP36388A or HP36398A). This type of backup is referred to in this
manual as an
online backup
.
• Using the ONLINE=START or ONLINE=END options:
Using the new functionality of TurboSTORE/iX 7x24 True-Online Backup, you can also
do an online backup of files and applications without requiring that files be closed for
write access at any time during the backup. This is referred to in this manual as a
7x24
