7signal Sapphire Carat User Guide Release 5.0
NOTE: use of backup systems requires 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 backup 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:
1. databases
a. measurement database
b. management database
c. security database
2. database logs
3. database backups
