Understanding your requirements and finding the perfect solution to fit

Backup

Backup to Cloud

Technology: Backup to cloud

Environment: All

Examples: Mozy, Assigra

Install Cost: Professional services required to setup and install agents and jobs, can typically be planned and completed within 5 Days (£3000)

Management: Very simple daily reporting sent to inbox. 

Running costs: 30-50p/GB/Month

Ease of Restoration: Usually a couple of click restore

Recovery point: Can be set to backup many times a day.

Recovery Time: The limiting factor is the bandwidth into the restoration centre

Retention: Many Years

Further comments:  Often very difficult to change vendors and migrate any existing data.  Can be expensive month by month, however the setup costs are low.  There are dozens of vendors competing in this space, so prices will decrease.  The major benefit is the lack of need to manage the solution, and the immediacy of getting you business data off-site. 

Backup of Virtual

Technology: Backup of Virtual environments

Environment: SME

Examples: Veeam

Install Cost: £4000 Licensing, £3000 Pro Services 

Running costs: £1000 \ year license

Ease of Restoration: Simple intuative interface

Recovery point: 

Recovery Time: 

Retention:

Backup to NAS

Technology: Backup to NAS Storage

Environment: Small or SME to Enterprise

Examples: Using Dell DR Series or Synology Diskstation

Install Cost: Can be set up in a variety of ways.  Looking at something like the synology, the device can be bought for around £1000 - it comes with it's own scheduled backup service and is capable to replicate to a second device, or to Amazon's cloud storage.  A good solution for a small business.

The Dell DR Series fits more comfortably with the SME to Enterprise space.  It requires some backup management software, but when configured can give large compression and de-duplication ratios - quoted by Dell as an average of 15:1.  Meaning that long term backup and retention to disk is a possibility.  unless situated in a separate location, this solution still requires a secondary off-site backup to take place, such as to-tape or to cloud. The product price starts at around £10000 for a 27TB model (giving roughly 405TB Logical Storage).  Adding to that the cost of the management server, professional services and a secondary offsite storage mechanism a project using this technology would be priced at around £30000.

Management:  The synology solution requires very little management other than the occasional tidy up of files being backed up, and a test restore.

The Dell Solution would require a skilled It professional to carry out monitoring and maintenance tasks as well as restores.

Running Costs:  If using a secondary backup to the cloud with the Synology our finger in the air estimate of to cloud backup costs are about 30p/GB/Month.  For a typical storage of around 2TB this would cost about £600 \ month.

The Dell Solution would have the same running costs as our to tape solution (£2000), plus a similar figure for warranty on the hardware (£2000). Replicating to the cloud rather than to tape would reduce the solution cost initially by about (£5000), however the monthly cost would be significant.  Replicating to a co-located datacentre with dedicated hardware would work out as a far more cost effective and flexible option.

Ease of restoration: The synology solution would require a couple of clicks from a user friendly menu to recover files.

The Dell solution would require a skilled technician to carry out a restoration - however it would be fast in comparison to tape.

Recovery Point: These solutions are fast to backup and restore and can be run at intervals such as hourly throughout the day

Recovery Time: Can recover files or servers from a few minutes to an hour.  Multiple jobs can run concurrently being beneficial in the case of a total disaster.

Retention: In isolation a NAS device can retain many months worth of data. Used in conjunction with a secondary storage medium, this can be many years.

 

Further comments: For a small business this type of solution can be quick and easy to implement, however as the size of the environment scales the costs and complexity jumps up significantly.  A hybrid solution gives the best of both worlds in terms of backing up and restoring data rapidly as well as giving long term retention.

Backup to Appliance

Technology: Backup to Appliance

Environment: SME

Examples: Barracuda 490, CommVault

Install Cost: £6500 for an all-in-one Barracuda appliance, £3000 professional services.  Other Vendors can be significantly more.

Management: requires a skilled Technician to administer

Running costs: 20% annual Software assurance and licensing (£1200)

Ease of Restoration: Intuitive interface.

Recovery point: Can be run multiple times throughout the day (Hourly) 

Recovery Time: Minutes to an hour, multiple concurrent restores possible

Retention: Up to a couple of months

Further comments: With these devices, you don't have the overhead of needing to setup a separate management server and buy multiple additional add on licenses. 

Tape Backups

Technology: Tape Backup with Symantec backup Exec

Environment: Any size

Examples: Using Symantec Backup Exec installed on a management server to backup to a tape library.

Install cost: Requires a management server - £2k, a tape library (About £3000 for a Dell Power vault library containing 24 Tapes), Software costs (About £3k to backup 10TB of mixed servers), Professional Services (About £3k - planned and installed in 5 Days). Fire Safe £1k Total: £12k

Management: Requires software to be monitored and tapes to be taken regularly to a safe location

Running Costs: £35 \ Tape - usually another 12 each year (£420). License support \ Software Assurance and hardware maintenance at 20% (£1600)

Ease of restoration: Requires Tapes to be loaded and a trained technician to recover, however there are lots of recovery options from whole servers to individual files and emails. In the event of a loss of building new tape hardware would be required.

Recovery Point: Typically current to the evening before

Recovery Time: Can take a few minutes to restore a couple of files from a tape still in the library to an hour for the same task to locate a tape from the "safe" location, load it into the library and recover.  A typical server will take a couple of hours to recover.  A site of about 20 Servers would take several days assuming hardware is available.

Retention: Many years.

Further Comments: Great for long term retention, not good for fast recovery from a recent point in time, however lots of recovery options.
