A mass storage backup system is available on ECN for backing up workstation and server disk drives running Windows, Solaris, HP, SGI and IBM AIX. All file changes are copied to tapes in the library daily. These Daily copies are stored for three months. Complete copies of disks are archived for long term storage twice per year, in July and December. Files or complete disk may be restored upon request to ECN staff.
Retrieving a lost file
The ability to provide tape backups of user data files was recently enhanced by the installation of a new tape library system. The base model of the ADIC Scalar 10K is now in service in the ECN central machine room. The initial configuration consists of 700 tape slots, two LTO-2 and 6 LTO-3 tape drives. Each LTO-3 tape cartridge has an uncompressed storage capacity up to 400 gigabytes. The library, with LTO-3 tapes has a capacity of over 350 terabytes and is expandable.
Cost of backup services
Tape supplies must be purchased for each workstation and server, a software license** may also be required. The current cost of tape supplies is $10.00 per GB of formatted disk capacity. For example: The cost to add an office PC with 40 GB disk to the backup system would be:
$400.00 (40 * $10.00) plus the client license. This is a one time fee per disk added to backups. Media fee is for the life of the disk. If the disk is replaced for larger capacity, a new media charge is assessed. The original media fee does not carry forward.
How to get backup services
Engineering users may request backup services by completing the Backup Request Form.
Each workstation and server owner is responsible to purchase a software license and initial tape supplies. Workstations must be powered on and network accessible by the backup system during the evening hours. Persons designated to receive error reports will be notified by email when backup of a system fails. It is that person's responsibility to determine the reason for the failure and notify ECN if assistance is needed to return the machine to a state that allows backups to succeed. All disk capacity and volume name changes must be reported to email@example.com before backup of the affected disk can be assured.
**Software license cost is one time and licenses are transferable to other machines.
