HANA backups

HANA backups

Backups are important for disaster recovery, you have to make sure that DATA and LOG are saved regularly.
This monitor will look for the time elapsed between last backup as well as backup size and duration.

Configuration hints

DATA backups

Use alarm/metric/report checkbox to enable sending alarms, metrics or report customization for DATA backups
Define backup error severity to receive alarms when a backup has failed.
Define Max backup duration severity
Define max time since last successful backup

LOG backups

Use alarm/metric/report checkbox to enable sending alarms, metrics or report customization for LOG backups
Define backup error severity to receive alarms when a backup has failed.
Define max backup duration threshold and severity
Define max age of last successful backup and severity
Expected log mode: You can define the expected log mode and get an alarm if the current mode is not as expected
Automatic log backup: You can define the expected automatic log backup setting and get an alarm if the current setting is not as expected

Backup duration/age threshold

If you set an absolute number or a number with units like (m, h, or d for minutes, hours, days), an alarm will be sent if threshold is reached, using configured severity
If you set a multi-threshold syntax (ex: G2W:30 W2M:60 M2C:120), the thresholds must be set in minutes.

Backup size

For each type of backup, you can monitor file size and get notified when threshold is reached.
Just select the backup type

Note:

You can disabled a check by setting its threshold to 0 or setting its severity to disabled.

Surveillance table

Parameter	Description
Active	If checked, the rule is enabled and will be processed
Host	Can be used to restrict the monitoring to a given host (multi instance case). A star (‘*’) will matchany host.
Service	: Defines from which service the backup files will be checked. A star (‘*’) will match any service.
Backup type	The type of backup.
Max size (TB/GB/MB)	The maximum file size. Unit can be specified: TB, GB, MB or KB. If no unit specified, the valuewill be assumed as bytes. If set to 0, the size won’t be monitored.
Severity	Defines the level of severity of the alarm that will be generated if one of the thresholds isreached.
Alarm tag	You can define some text to use as a prefix of the alarm message generated by the current rule.
Alarm	Defines if an alarm/metric has to be generated for the given rule.
Metric	Defines if an alarm/metric has to be generated for the given rule.
