Data Protection for Today’s Economy: Amber Road and Zmanda

Monday, November 10th, 2008

Today Sun announced the new 7000 line (aka Amber Road) of open storage appliances. Amber Road runs OpenSolaris and ZFS on industry-standard x86 hardware and includes innovative management software developed by Sun’s FISHworks (Fully Integrated Software and Hardware) group.

Our engineers worked along with Sun’s technologists on Amber Road in Sun’s labs for past few weeks, and today we are announcing support for Amber Road with both of our products Amanda Enterprise and Zmanda Recovery Manager for MySQL.

Amber Road is another example of innovation and value created by combination of open source and open systems. Combine  Amber Road with Zmanda’s open source backup products and you can deploy an extremely scalable and blazing fast backup solution at 1/5th the cost of products from proprietary vendors. We are also offering a free 60 days trial to all Sun Storage Systems customers (please contact your Sun or Zmanda sales rep for this).

Amanda and Grandfather-Father-Son (GFS) backup tape rotation

Tuesday, November 4th, 2008

The GFS tape rotation scheme is a popular method of maintaining backups on a daily, weekly, and monthly basis. The primary purpose of the GFS scheme is to suggest a minimum standard and consistent interval at which to rotate and retire the media.

In general, GFS backup schemes are based on a seven-day weekly schedule beginning any day. A full backup is performed at least once a week. On all other days, full, partial, or no backups are performed. The daily backups are the Sons. One full backup in the week (the weekly backup) is the Father. One full backup of the month (the monthly backup) is the Grandfather. GFS rotation schemes allow you to back up your servers for an entire year using a minimum number of media.

Amanda can be used to implement GFS tape rotation schedule. User can implement three backup sets for daily, weekly, monthly schedule. An example for 5 day GFS tape rotation is explained below.

Daily full/incremental backup on Mon-Thu, weekly full backup on Fridays and monthly full backup on first Friday of the month.

  1. Daily backup set is scheduled to run weekdays (M-Thu). The Amanda strategy is set to “inconly” and a tape rotation cycle of 4.
  2. Weekly backup set is scheduled to do backup on all Fridays except first one in the month. The Amanda strategy is set to “noinc” and a tape rotation cycle of 5.
  3. Monthly backup set is scheduled to to backup on first Friday of the month. The Amanda strategy is set to “noinc” and a tape rotation cycle of 13.

Amanda enterprise management console allows the administrator to identify the media volume that was used for the backup, media volume that will be used next and also information about client, media backup failures.

Users can move tapes from daily backup set to weekly backup set and from weekly backup set to monthly backup set to reduce the wear/tear on the media.
