Hard Lessons Learned

Tape Saves the Day…Provides Offline Protection

Ben Treynor, VP Engineering and Site Reliability Czar for Google Gmail, used the official Gmail blog to explain the situation where some users lost access to their email accounts during a software update that was buggy.

“I know what some of you are thinking: how could this happen if we have multiple copies of your data, in multiple data centers...well, in some rare instances software bugs can affect several copies of the data. That’s what happened here. Some copies of mail were deleted...To protect your information from these unusual bugs, we also back it up to tape. Since the tapes are offline, they’re protected from such software bugs”.

Storage Issues

Best Practices in Data Protection

Have multiple copies or layers of protection: depending upon value of data, keep at least 3 copies, keep in different locations; one out of region – Use disk and tape

Isolate one copy: at least one copy offline for logical system isolation to avoid intentional or unintentional corruption that can occur with online storage - Use tape; Keep offline

Have technology diversification: copies on different forms of media to avoid a media or system process disaster - Use disk and tape

Protect access to data: at rest and in transit – Use encryption & WORM

Manage backup differently than archive:

– Backup multiple, point in time consistent copies for operational and DR recovery consistent with application specific RTO/RPO - Use disk and tape

– Archive single instanced data for long term retention: combination of disk & tape

Large Truck Express Line Survives Hurricane Flood

Business Challenge: • Hurricane Gastone flooded Data Center with 5 ft. of water • Total loss of hardware, networks, phone systems,

generator, and utility power • Good news: a tape backup of 100% of the data was

made the night before – stored off site!

Solution: • Protect assets and business resilience with comprehensive best practice strategy • Create nightly disk flash copy for fast retrieval and window-less backup to tape • Backup 100% production data to LTO tape library nightly: tapes moved offsite • Global Mirror DR site and backup to LTO tape library – Lights out! • Creates 5 copies of data (2 offline on tape in different remote locations)

Benefits: •Able to control TCO, access data and protect data with tiered storage strategy •No production system interruption •No save window-Set it & forget it •No production cycles, no operators, lights out operations •Logical data protection and out of region protection

“The reports of tapes demise are

grossly exaggerated,”

(borrowing a phrase from Mark Twain)

“Tape is cheap, safe and reliable and there is no

substitute….the archive data backstop.

It is the data centre's lifebelt and lifeboat.

Without it, when the data loss/data corruption

storm strikes, you are sunk. It's that simple.”

Chris Mellor “Tales from the Storage Frontier” May 2011

It’s reliable high speed and capacity

– Streams very fast and stores high capacity

– Read after write verification for reliable writes

– Servo tracking to help ensure precision tracking

– Better bit error rate than disk! 1x10E17 bits vs. 1x10E15 bits

It’s Cost-effective and Green

– Lowest storage cost for the foreseeable future

– Most energy efficient method of storing digital data

– Cartridges on a shelf consume no energy

It’s scalable

– Easy to add additional storage (i.e. add cartridges)

– Tape provides “infinite capacity” on demand

It’s removable / transportable / shareable

– Off-line and off-sight storage for data protection-archive

– Cartridges are easy to ship (XX PetaBytes / Day)

But tape is difficult to use!

– Tape automation has simplified the process

– LTFS makes tape easier to use than ever before

Why is LTO Tape on the Storage Hot List?

And easy

Tape Reliability Soars

Both disk and tape have made significant reliability

improvements in recent years. For tape, reliability progress

has been even better than disk comparing the BER (Bit Error

Rate), which is quickly becoming a more popular means of

measuring reliability.

Source: Tape Storage Future Directions and the Data Explosion

Fred Moore, President, Horison, Inc. 2011

BER is the percentage of bits that have errors relative to the total number of bits received in a data

transfer

■ A open software specification that allows simple and new

ways of accessing data on tape (LTFS spec doc available at: www.ultrium.com/ltfs )

■ Self-describing tape format to address data archive

requirements

■ Implemented on dual-partition LTO-5 tape

■ First partition holds the tape index / metadata

■ Second partition holds the content

■ It presents a tape as an extension of the operating system:

appears as another drive letter, icon or folder like a disk or

memory stick

What is the Linear Tape File System?

LTO Tape Joins the Ranks of Easy to Use Portability

http://www.ultrium.com/ltfs

30

LTFS: What are the potential benefits?

•Improved archive storage -“Memory stick like” self describing file system -Tape can tell you what’s on it now and in the future -Up to 30 year shelf life

•Easy to use -View contents in OS browser directory tree -Simple “Drag & Drop” movement of data

•Increased data mobility-portability -Compatibility across OS environments -No backup/archive software needed to view content -A single storage media standard -File, HW, SW and camera agnostic

•Reduced costs and energy consumption -LTO tape is less expensive than other storage formats -Tape is “green”…a cartridge draws no power!

"I am shocked!

This is exactly

what we need!"

"LTO-5 technology

gives tape-less

work-flow....with

tape!"

"Now I can offer an

LTO-5 archiving

service to my movie

clients."

LTFS: How does it work?

• LTFS utilizes media partitioning (new to LTO Gen 5)

• Tape is logically divided “lengthwise” into two partitions

- Index partition: File system info, index, metadata (37.5 GB)

- Content partition: Contains the files / content bodies (1425 GB)

When mounting the tape, the Index is copied to the workstation/server

memory for fast access and updates

Periodically the index is backed up to the content partition
