Backup Interfaces

Backup and restore are both controlled entirely through the LogLogic appliance GUI Administration > Backup/Restore Configuration page.

The only exception is that before running an SCP backup for the first time you must configure SCP through the appliance CLI.

The Backup Configuration tab is accessible through the GUI on LogLogic LX Appliance, LogLogic MX Appliance, and LogLogic ST Appliance.

Use the Backup Configuration tab to specify settings for saving a backup copy of your appliance log and configuration data. The default settings for backup method are None and Optimize.

Note: Your backup location must support hard links.

Select SCP to back up any server which supports SCP with a user name, typically any UNIX or Linux system.

Select SAN to backup any volume on the appliance to a Storage Area Network (SAN) device available to the appliance. SAN backup is available only on LogLogic ST Appliances.

If the Optimize check box (the default setting) is selected, it indicates that the appliance performs incremental backups instead of a full backup each time. An incremental backup copies only data that has changed since the previous backup, as opposed to a full backup which copies everything each time. These optimized backups save a lot of time for each backup, but still provide full restore capability if needed.

Note: The initial backup for the appliance is always a full backup.

Bypass disk space checking — Because the LogLogic application is very conservative, and because the total space required for backing up logs is difficult to accurately predict, the system might state that not enough storage space is available for backing up your log files when in fact you know that sufficient space is available. The default condition for this check box is not selected, meaning the appliance calculates (and possibly overestimates) the amount of backup space required. LogLogic estimates the space required based on the number of backups specified to be retained. For example, if 3 backups are specified, LogLogic estimates the disk space required for 4 backups. This is because the first (oldest) backup is deleted only after the fourth one is complete.

If the Bypass disk space checking check box is selected on the Backup Configuration pane, it prevents the appliance from possibly overestimating the amount of storage space necessary for a full backup of your log data.

If the Config only check box is selected, the appliance backs up only the configuration data on the appliance.

You can schedule regular backups to run at a specific time regularly on any days of the week, or to run daily at that time.
