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”.

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.”

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.

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?

(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

"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

(31)

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
