DiskBased Storage Units (04/24/2008)
(...) We will use VERITAS NetBackup for any specific examples, but we believe the concepts can carry over to any other solution that supports disk-based backup. Since disk-based storage is finite, you really need to take into consideration how you will manage it once your backups are on this device. More importantly, you need to determine which clients you want to back up to it. (...)

Using the Activity Monitor (04/19/2008)
(...) From the Activity Monitor, you can cancel individual jobs or cancel all running jobs. This is done from the Actions menu at the top of the screen. There are additional fields that give information about each job, including the actual policy name and schedule for backups, start time, elapsed time, media server name, client name, end time, number of this attempt, and others.

Define some storage media to be used for the backups (04/18/2008)
(...) You are even given the opportunity to identify cleaning volumes that might be in the library. As you add volumes, either manually or via the wizard, you should ensure that the media type for the volumes matches the media type for the drives. Note that there are three different DLT designations, since a single library could contain a mix of DLT 4000, DLT 7000, and DLT 8000 drives. (...)

Evaluating Storage Media Requirements (04/17/2008)
(...) That is why we picked a starting point of analyzing the data and moved forward from there. As you move forward with evaluating storage media, you need to consider the selection of a suitable drive technology. The number of different drive types and the number of different libraries that support the different drives complicate this decision. (...)

Specific NetBackup Configuration Elements (04/17/2008)
(...) We will use VERITAS Software's NetBackup application for this discussion. In this article, we go through the unique terms and concepts that apply to NetBackup so you can follow the examples more easily. We look at the elements that go into the selection of a master server, to determine if separate media servers are required, and at the actual steps involved in configuring the storage devices for use by NetBackup, as well as configuring a policy to back up clients.

Layout NetBackup Domain (04/16/2008)
(...) If it looks like there are a lot of network-based clients on slow networks, you should consider installing a high-speed backup network. This gives you increased backup and recovery performance, as well as keeping backup and recovery traffic off the production network. It is now common to install a 100Base-T or Gigabit Ethernet network just as a backup and recovery network. (...)

Frequency of Backups (04/15/2008)
(...) The decision between differential incremental and cumulative incremental is based on recovery requirements versus media usage. Weekly full backups and daily differential incremental backups could require up to six tapes to restore a directory, filesystem, or database in a worst-case scenario. Each of the incremental backup images might be small, but each day's changes could be on a separate tape, or at least different images on the same tape. (...)

Off Site Storage Requirements (04/15/2008)
(...) This usually depends on why the data is being stored off-site. If there are legal requirements, then these requirements usually stipulate how many copies. If it is being done for pure DR, one or two copies might be adequate. (...)

(...) To this, he answered that configuring for backups was on his 'list of things to do.' If a storage area network (SAN) is available, it can allow for more flexibility in the backup and recovery strategy. The backup hardware can be better shared amongst the large data-resident systems while still keeping the data off the production LAN. (...)

Complexity in enterprise backup (04/13/2008)
(...) Enterprises with many information services are likely to use multiple data management systems (filesystems and database management systems), each with its own mechanisms for backing up data objects that it recognizes. Your task is integrating these mechanisms into a schedule that provides a consistent backup of all required data for a service and keeping them up-to-date as the service changes. Continuous availability. (...)

Conceptually a backup strategy is simple (04/12/2008)
(...) The results of these reports should also help define the recovery window, should this particular business unit suffer a disaster where data cannot be accessed or updated. Knowledge of these requirements may, in fact, change the entire budget structure for your backup environment, so it is imperative during the design and architecture phase that you have some understanding of what the business goals are with regard to recovery. You will find that most business unit managers are not as concerned about backup as they are with recovery. (...)
