How to get SCSI reliability on a SATA budget
Serial ATA (SATA) disk drives combine the low price of IDE drives with longer cabling and better adaptability to RAID arrays than their Parallel ATA cousins. As a result, SATA drive arrays are becoming increasingly popular for building inexpensive drive arrays, especially in iSCSI SAN applications.
Vendors shrink D2D archiving boxes for smaller shops
IBM and EMC Corp. announced lighter versions of their respective disk-based archiving products this week, recognizing that the current versions of these systems are not getting traction with smaller companies.
Seven ways to minimize tape failure
Tape backup is still the most frequently used backup method for business users because of its cost-effectiveness per megabyte of data, despite the increasing popularity of recordable CDs and DVDs. However, just like any technology, tape drives, backup tapes and tape backup software can fail.
Making disk-based backup work
For those struggling with nightly backups, the arrival of low-cost disk promises to be the greatest breakthrough for improving the process since the introduction of centralized, networked backup in the early 1990s.
How to architect tiered backup with D2D2T
To figure out the true capabilities and limitations of current disk-to-disk-to-tape strategies, we have to examine actual implementations of products and talk to the folks in the trenches about what works and what doesn't.
Straight talk about D2D2T
Disk-to-disk (D2D), and disk-to-disk-to-tape (D2D2T) have taken the center stage in industry discussions around data protection. Both technologies leverage a multi-tier architecture fielded either with the intention of improving the performance of backups in production environments, or to expediting restores in the wake of a primary storage failure or accidental file deletion.
Cheap SATA spurs D2D
Two vendors are capitalizing on falling disk prices to create disk-to-disk (D2D) backup appliances that complement -- and in some cases replace -- traditional tape backup.
How long does tape last, really?
The most commonly quoted figure for the archival life of magnetic tape is 30 years. Even in an era of heightened concern about compliance and records retention, that is long enough to make storage administrators comfortable -- perhaps a little too comfortable.
The dirt on WORM tape
Although most people still think of WORM (Write Once Read Many) as a form of optical disk storage, tape WORM is an increasingly popular option.
Pros and cons of remote mirroring for DR
What you will learn from this tip: The differences between synchronous and asynchronous remote mirroring, and when to use each as part of your disaster recovery strategy.
When -- and when NOT -- to use mirroring
What you will learn from this tip: Mirroring provides a failsafe for data, but it's not without its pitfalls. Here's when and when not to use the features of mirroring.
Alternatives to software mirroring
What's the best method for a total copy from drive 1 to drive 2, for the purpose of backup in case drive 1 gets corrupted? You know first-hand the downside of mirroring.
These mistakes can kill RAID dead
One of the main reasons to use RAID instead of JBOD is to improve reliability. With mirroring (such as RAID 1 or RAID 10), or striping with parity (such as RAID 5), the system can recover from a single hard disk failure with no loss of data.
How to maximize your mirrored tape controller
Most companies buy mirrored tape controllers to do exactly what the name implies -- make a mirrored copy of one or more tapes during the backup process. However, most of the products on the market can do other things as well. It's worth taking a look at what your mirrored controller can do to see if it can help you in other ways.
FAQ: Serverless backup
Many of the questions SearchStorage.com experts recieve is about serverless backup. These three questions and answers should help answer what serverless backup is, the difference between LAN-free backups and serverless backups and the best way to design a server free backup architecture.
School patches SAN failures with FalconStor mirroring
It sounds like the plot for a bad movie. A college student works tirelessly to finish a big exam or a thesis and at the last second the computer fails and everything is lost. Well, this nightmare became a reality at Cuesta College when a storage array failed and 100% of the student data stored on the network was lost.
EMC refreshes remote replication
EMC Corp. announced it will offer, in the first quarter of 2005, heterogeneous replication for its Symmetrix array enabling users to replicate data to IBM, Hitachi Data Systems or Hewlett-Packard Co. storage arrays, instead of another Symmetrix.
Server-based replication for Netware
I have an EMC CX300 SAN serving storage to NetWare 5.1 and Windows servers. I now want to replicate to another location, but the CX300 does not support array-based replication. Thus, I need server-based replication and I am struggling to find a tool for NetWare. Any ideas? Thanks!
Checklist: Ten steps to data replication
Data replication protects your data during a disaster and makes backups a snap, but with so many vendors in the space, and a variety of architectural approaches to the problem, how do you determine which data replication strategy is right for you?
Synchronous replication distance limitations?
I currently have two EMC Symmetrix systems talking over enrange to each other. The systems are about 200 miles apart. When we tried to do synchronous replication the production boxes were frozen. A few quick calls around suggested that there are distance limitations of around 100 Kilometers for the amount of bandwidth we are trying to do this over (T3). Is this true?
Remote replication gets out of the array
If you're a Symmetrix user and have stringent remote replication requirements, Symmetrix Remote Data Facility (SRDF) is pretty much the only game in town. But SRDF has its limitations: It's extremely expensive and only works within Symmetrix environments.
