requirement increases continuously.

NOTE: use of backup systems require planning and

administration i.e continuous effort from the

administrator. This area is outside of 7signal scope,

7signal encourages clear planning on the issue.

During installation there shall be various destination folders inquired by the install script.

The folders are for logs, for bakcup files etc. As complex as online backup may sound, the

setting of the online backup is easy. To maintain and keep it available and functional

requires IT support that is beyond the scope of 7signal guidance.

Behind the scenes the technology relies completely on IBM DB2 backup system and 7signal

provides interface that covers and automates IBM interface to support 7signal databases.

TIP: there are environments that require separate

hardware for backups. If possible, 7signal Sapphire

should be integrated (on file system level) to these.

TIP: with frequent and detailed automated reports the

loss of measurement data becomes less drastic as the

needed information may be found in the reports.

Changing log settings

Install time gives the option to set all the backup related settings including log setup.

To change the settings while the system is installed and in production later, please use the

tool 7db and the logsetup sub-command. Complete guide to 7db tool is in the appendix of

Deployment Guide.

Managing backup levels

By default the system is in default state, no automated backups at all. Any change to that

state would require more resources and administration that should be planned separately.

In case one has changed the default settings – either by giving such install parameters or

issuing the needed commands after the installation - the following operations return the

initial state:

1) stop circadian backups

2) set logging to circular mode

This implies that the default state means circular logging without circadian backups.

File system settings for the database

There are three elements that require – optimally separate – disk space:
