1. The problem, briefly stated

We need an easy, secure and efficient way to store all our files:

  • individual user files (backup)
  • shared project files (centralized storage and backup)
  • old user and project files (centralized storage and backup)

2. Current specifications our backup system

Most people use Bionet to backup their files.

Bionet

  • Storage space (as of 2007-01-16):
    • total: 110GB
    • used: 86GB
    • available: 24GB
  • Where is it physically located?
    Building 68, 3rd floor
  • Are Bionet files regularly copied and stored somewhere else?
    Yes, to the MIT datacenter in W91.
  • Problems with Bionet:
    • Not enough space to backup all our files e.g. microscope images
    • Isn't Bionet not going to be backed up anymore?
      This is currently (2007-01-23) unknown, will depend on the allocated budget.

3. Ideal specifications of our future backup system

(lab and individual data storage, sharing and backup needs - please list what would you like have available)

  • Capacity: we want to be able to store all files in a single location
  • Easy: automatic backup
  • Secure: the backup system shouldn't be located in building 68, in case of a fire
  • Efficient backing up or retrieving files should be speedy
  • Affordable

4. Potential solutions

The win.mit.edu Domain

MIT TSM Backup Service

  • Monthly service charge: $7.50 per month per computer
  • Storage limit?
  • TSM software is required to use the service and is available for Windows, Mac and Linux (free to MIT community per site license)
  • Backups are stored on one of the four TSM backup servers in building W91
  • Manual or Scheduled Backup
  • Old versions of current files and deleted files are kept for 30 days
  • Need a separate account for each computer to be backed up

Network Attached Storage

A Tale of Two Terabyte NAS Boxes

Buffalo Technology

  • Buffalo TeraStation Home
    • Example disk configuration: 4 x 250GB IDE (750GB in RAID5)
    • Protocols: FTP, SMB
    • USB 2.0 port for external hard drive (backup or additional storage)
    • Review by PC Magazine
      • Bottom line: Flexible and reliable storage for everyone on your network. Print sharing is a plus, as is expandable USB disk storage.
      • Pros: Offers RAID level data protection; easy-to-configure shared and private storage for all workgroup members; print sharing is a plus.
      • Cons: Large footprint. No logging or reporting features.
    • Review by ExtremeTech
    • TeraStation wiki
  • Buffalo TeraStation Pro
    • Released in March 2006
    • S-ATA drives
