Running Scheduled or Immediate Backups

You can schedule a backup to run on specified days or run a backup immediately.

1. In the appliance GUI, go to Administration > Backup/Restore Configuration.
2. Select the backup method:
   • NFS
   • SCP
   • SAN (This option is available only on LogLogic ST SAN appliances.)
   • Amazon S3
   A section with fields specific to the selected backup method is displayed.
3. (Optional) Select to Optimize the backups so only incremental backups are run 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.

   Note: This option is not available for Amazon S3.
4. (Optional) When the Bypass disk space checking check box is not selected (Default), the system checks for available backup space prior to backing up your log files.
   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 cleared, meaning the appliance calculates (and possibly overestimates) 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.

   Note: This option is not available for Amazon S3.
5. (Optional) Select the Config only check box to back up only the configuration data of the appliance.
6. Depending upon the backup method you selected, enter the following information:

   Backup method	Fields/tasks	Description
   SCP	User Server	Enter the username and server IP address.
   NFS	NFS Server	Enter the server IP address
   SAN	In the Device pane, view the Host Bus Adapters (HBAs) and World Wide Port Number (WWPNs): Hover over the HBA to reveal the local port number assigned to it. Click + to reveal the disks attached to the HBA. Hover over disk numbers to see attached labels. Click a disk to display (in the Information pane) its operational status, size, and the Linux device mapped to it. (The UUID and Label fields are not used.) Click + again to reveal the disk partitions and sizes. Hover over 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 must 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 pane 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 button above the Device pane, and enter a label for your backup. Click OK to close the window, or Cancel to close without saving.
   Amazon S3	Identity	Select Identity and Access Management (IAM) User or IAM Role as per the permissions assigned to you by the administrator.
   	AWS Access Key ID AWS Secret Access Key	Enter the AWS access key ID and secret access key of the AWS console.
   	Role ARN	Enter the Amazon Resource Name (ARN). This field is displayed only if you select identity as IAM Role.
   	Amazon S3 Bucket Name	Enter the bucket name where you want to back up the appliance data.

7. Set the backup to automatically run as per a schedule or to run immediately:
   • Select the recurring Backup Schedule days and time.

     Select the days of the week on which you want automatic backups to occur, or select Everyday.

     Set Backup Time for the automatic backups to begin on the selected days. Appliance data is backed up on the selected days and at the beginning of the scheduled hour.

   • If you want to run a backup immediately, select Start Backup Immediately.
8. Select the number of Backups To Retain that can be available later for restoring. The maximum is 30.
9. Click Update to save the backup configuration.
