====== Level 1 Backup on SME 8 ======

:!: These notes have been tested only on SME Server version 8, but they will probably work on SME 7 as well.

===== Multi-Level Backup System =====

These notes pertain to configuring what we call "Level 1" backups in a multi-level backup system. We are referring to a backup system that uses a local hard disk to back up server data as well as an on-line backup service for off-site storage.

  * **Typical Scenario**
     * Software RAID 5 for primary storage
     * Separate hard drive for backups
     * Hard drive only mounted during backup
  * **Level 1 Backup**
     * Uses local hard disk
        * Fast backups
        * Minimal 'backup window' required
        * Fast and convenient restores
        * Disaster recovery
  * **Level 2 Backup**
     * Uses on-line backup service
        * Slower than level 1
        * Off-site storage
        * No hardware required

===== Prepare a Separate Backup Hard Disk =====

The following operations are performed at the console as root.

==== Prepare the Separate Backup Drive ====

See also **[[computing:storage:disk_partitioning|Advanced Format (4K Sector) Drive Partitioning]]**

<file>
fdisk -l                             # Determine which drive is the backup drive - Be sure!
fdisk /dev/sdx                       # Add a partition
mkfs.ext3 -m 1 -L backup /dev/sdx1   # Label and format the partition
</file>

:!: For very large drives, the ''-m 1'' switch reserves only 1% of the disk space as reserved blocks.

==== Mounting the Separate Backup Drive ====

Here we configure SME Server to mount the L1 backup drive in the same place every time.

<file>
mkdir /media/backup             # Create a mount point
vim /etc/fstab                  # Modify /etc/fstab and add a line for your drive
                                # The drive is not auto-mounted or fsck'd

LABEL=backup            /media/backup           ext3    defaults,noauto 1 0

mount /media/backup             # Test the mounting
df -h                           # Show the new filesystem
umount /media/backup            # Unmount the new filesystem
</file>

Before continuing to the configuration stage, you must reboot.  Otherwise, the new backup disk will not be available as a choice of disks to back up to.  If you see the Backup share set to nolabel, you forgot to reboot.

<file>
reboot
</file>

===== SME Server Manager =====

==== Configure Workstation Backup ====

:!: Settings will vary! This example is for a dedicated internal level-1 backup drive.

:!: A set is a full backup plus incrementals.

^Item                               ^Setting         ^
|Configure Workstation Backup       |Local USB Disk  |
|Backup share                       |backup          |
|Number of rotating backup sets     |4               |
|Daily backups in each set          |7               |
|Workstation backup time of day     |10:00 PM        |
|Optional backup session timeout    |8               |
|Don't timeout full backup sessions |selected        |
|Backup compression level           |6               |
|Full backup is allowed on          |Sunday          |

=== Problems Due to Firefox ===

:!: This problem has apparently been fixed in newer updates of SME 8.

<file>
vim /home/e-smith/db/configuration
</file>

Search for 'backupwk' and edit the line to remove "^M"
