TurboSTORE/iX 7x24 True-Online Backup Options

This section discusses the new options available for creating TurboSTORE/iX 7x24

True-Online Backups.

Creating a TurboSTORE/iX 7x24 True-Online Backup (ONLINE)

A TurboSTORE/iX 7x24 True-Online Backup is performed only when either the START or

END parameter is included with the ONLINE option.

If no parameters are speciﬁed for ONLINE, the sync point automatically occurs at the

beginning of the backup, and an online backup is performed where all ﬁles must be closed

for write access at that time.

Up to 15 TurboSTORE/iX 7x24 True-Online Backups can be running at once. Also, a ﬁle

can be stored by up to 15 7x24 true-online backups.

Initiating a TurboSTORE/iX 7x24 True-Online Backup (START and

END)

The initiation of a 7x24 true-online backup with a logically consistent sync point is

controlled by the START or END parameter with the ONLINE option. Backups created with

the START parameter have the sync point at the beginning of the backup. Backups created

with the END parameter have the sync point at the end of the backup.

Specifying Time

In addition to the START or END parameter, you can specify a time for the sync point to

occur. The time is speciﬁed in 24-hour format (hh:mm[:ss]). If a time is speciﬁed with END,

the sync point occurs at the time speciﬁed or once all ﬁles have been stored, which ever

event occurs last. If a time is speciﬁed with START, the sync point occurs at the time

speciﬁed, or once all ﬁles are prepared for the backup, which ever event occurs last.

For example, you can initiate a backup with the following command:

:STORE /;*tape;ONLINE=END,17:30

If the backup completed at 17:00, TurboSTORE would continue to log changes until 17:30.

It would then synchronize the databases and write the log data to the backup media. If, on

the other hand, the backup did not complete until 18:00, TurboSTORE would delay the

sync point until 18:00. See the "Synchronizing Multiple Applications" section later on, for

more information on synchronizing all applications.

Prompting During Backup (ASK)

If you want to be prompted during the backup to manually quiesce any other ﬁle types

and/or third-party databases that are not automatically synchronized, you can use the ASK

parameter. ASK makes TurboSTORE wait for you to ﬁnish these operations.
