What do audits have to do with – Large Data Sets?
• Both audits and disaster recovery require IT professionals to
adhere to IT best practices.
• The biggest difference is one you are held accountable by an
external audit team and the other you are held accountable by
your boss.
• Both require risk mitigation.
• Both require testing.
• Both require the IT professional to do a point in time data recovery.

Large Data Sets – Tape vs. Cloud
In today’s discussion we are going to compare and contrast the difference between
storing 2TB of data to tape versus cloud.

•

If we look at tape first, specifically LTO-5 tapes, we should
consider several things.
–
–
–

How long the backup will take?
How many tapes will you need for a full and incremental
backup?
Where are you going to put those tapes when your backup
has completed?


WWW.ZETTA.NET

Large Data Sets – Tape Backup
• A 2TB backup using LTO-5, uncompressed, will
require 2 tapes for every full backup.
• If the daily rate of change of that data is 25%, we are
looking at an additional 500 GB of data that needs to
be transferred to tape every day.
• If you are limiting your failure domain, we will swap
out those tapes daily, thus leaving you with 8 LTO-5
tapes used every week.
• Being fearful of having your primary and secondary
copy of data on site, you have taken the precaution to
have your tapes brought offsite on a daily basis.

WWW.ZETTA.NET

Large Data Sets – Tape Recovery
• Now, on day-6 you encounter a disaster and you need to recover your
data.
• Your IT team now makes an emergency call to your offsite data vault
and has an out of cycle tape delivery made to your office.
• You are now 5 hours into the recovery. One hour to diagnose the issue
and 4 hours to have the tapes brought back in.
• First you load up your last full backup and restore your 2TB of data.
• The recovery process incremental and then overlay your tapes until
you reach tape 6 and then, at this point in time, you are have recovered
your data.


WWW.ZETTA.NET

Tape Recovery – Post Mortem: Time
• This Example Tape Recovery took 15 hours.
• 1 hour to diagnose the problem and figure out
what tapes you need to recall
• 4 hours for the tape to be recalled
• 4.5 hours to restore the full backups
• 5 hours to overlay the incremental backups to
bring you back to your RPO ( Recovery Point
Objective).

Tape Recovery – Post Mortem: Cost
Tape Recovery Costs:
•LTO-5 Tape Cost - $30 * 8 =$240 / week
•Tape Drive Cost - $3,000
•Tape Offsite (8 tapes) charge = $20 / Month
•Backup Software - $15,000
•Emergency Recovery Charge - $300
•Data Center Costs - $200 / Month
•Hardware Support Costs - $600/year
•Software Support costs - $3,000/year
•Server Engineering time - $20,000/year
•Tape Risk - significant

Tape – Common Issues
Common issues when dealing with tape:
•Tape header corruption due to tape drive failure
•Tape media stretched or snapped
•Media surface damage
•Reformatting or erasure of tape
•Overwriting of tape headers
•Tape backup software corruption
•Random CRC Errors reported
•Unable to catalogue media
“Having to go to my bosses’ office and tell him that I can’t recover the
data, is not a conversation I want to have.”

Cloud Disaster Recovery – vs. Tape
“So Rich, what are the
biggest differences between
using tape, disk, or cloud for
offsite backup & DR?


WWW.ZETTA.NET

Cloud Backup – Can it work?
The 2 types of cloud backup: SMB vs. Enterprise-grade
Example 1: SMB Backup
Example 2: Enterprise-grade Cloud
Backup

The Math: 100GB/day
2TB initial backup = 20 days
6% daily change rate = 120GB

The Math: 5TB/day
2TB initial backup = 9.6 hours
6% daily change rate = 120GB

120GB daily incremental = 28.8 hours

120GB daily incremental = <1 hour

Does not work.

Works!
