Multi-Level Backup System

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

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.

  • 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
  • Typical Scenario
    • Software RAID 5 for primary storage
    • Separate hard drive for backups
    • Hard drive only mounted during backup

Prepare Backup Hard Disk

The following operations are performed at the console as root.

Prepare the Separate Backup Drive

fdisk -l                        # Determine which drive is the backup drive - Be sure!
fdisk /dev/sdd                  # Add a partition
mkfs.ext3 -L backup /dev/sdd1   # Format the partition
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 -T                           # Show the new filesystem
umount /media/backup            # Unmount the new filesystem

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.

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

A set is a full backup plus incrementals.

  • 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
