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.
- 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
4. Potential solutions
- 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
- 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.
