Running Scheduled or Immediate SAN Backups

You can schedule an SAN backup or run an SAN backup immediately.

1. In the appliance GUI, go to Administration > Backup/Restore Configuration.
2. Select the SAN radio button.
3. The SAN backup options appear.
4. (Optional) Select the Optimize check box to perform incremental backups instead of a full backup each time. An incremental backup copies only data that changed since the previous backup, while providing full restore capability if needed. This saves a lot of processing time for each backup after the initial backup for the appliance.
5. (Optional) When the Bypass disk space checking check box is not selected (Default), the system will check for available backup space prior to backing up your log files.
   Note: Because the LogLogic application is very conservative, and because the total space required for backing up logs is difficult to accurately predict, the system may 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 checkbox is unchecked, meaning the appliance will calculate (and possibly overestimate) the amount of backup space required. 



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

6. In the Device pane, view the Host Bus Adapters (HBAs) and World Wide Port Number (WWPNs).
   • Rollover the HBA to reveal the local port number assigned to it.
   • Click + to reveal the disks attached to the HBA. Rollover disk numbers to see attached labels.
   • Click a disk to display (in the Information pane) its operational Status, Size, and Linux Device mapped to it. (The UUID and Label fields are not used.)
   • Click + again to reveal the disk partitions and sizes. Rollover partitions to see attached labels.
   • Click a disk partition to display (in the Information pane) its operational Status, Universally Unique Identifier (UUID), Label, Size, and Linux Device mapped to it. The partition is what the user will choose to back up to, not the actual disks themselves.
   • The Current Configuration window shows the target Disk and Partition selected for backing up to. If the window is blank, no Disk and Partition have been selected yet.
   • To select or change the target Disk and Partition, click a partition in the Device window and roll your mouse over it to reveal the presence of a label. If no label appears, check the partition size in the Information window.
   • If the partition size is adequate for backing up your log data, click the Label icon over the Device window, and enter a label for your backup. Click OK to close the window, or Cancel.
   • Click the Update button at the bottom of the page. The message: Backup configuration update completed will appear at the top of the Backup Configuration page, just under the tab.

     However, if you see: SAN Config: The selected device can't be used for SAN... or... SAN Config: The selected device conflicts with an existing backup/restore configuration, select another partition and try again.

7. Set the SAN backup to automatically run on a schedule or to run immediately:
   • Select the recurring Backup Schedule days and time.
   • Select the day(s) of the week on which you want automatic backups to occur, or select Everyday.
   • Set the Backup Time for the automatic backups to begin on the selected days.
   • Select Start Backup Immediately under Backup Now.
8. Select the number of Backups To Retain that can be available for restore, from 1 to 30.
9. Click Update to save the new SAN backup configuration.

   The backup process creates an additional folder using the appliance IP address to avoid an accidental overwrite by another appliance.

   The interface displays, “Backup configuration update completed.” Appliance data is backed up daily at the beginning of the scheduled hour.

   To disable backup on this appliance, under Backup Method select None.
