Product Code: R3428-3Description This study discusses the results of a survey that was completed in November 2006. The survey addressed the evolution of backup process at sites having 1 TB to 1 PB of storage capacity, with emphasis on the shift from disk to tape, and a focus on VTL implementations, plans and selection criteria.
As disk-based backup is booming and tape refuses to die, VTL leads the way in terms of disk-based backup adoption in all business tiers, but the growth is particularly promising in the medium size sites, sites with 10 to 200 TB of raw disk capacity.
x percent of the surveyed sites have implemented VTL today, and x% will either upgrade their installation or acquire VTL for the first time in the next 12 months, bringing VTL on par with D2D. D2D will continue to prevail at sites with disk capacity over 200 TB and under 1 TB.
The percent of managers wishing they can get rid of tapes, has risen from 57% last year to x %. y% estimate the timeframe for a tape-less operation to be less than 4 years, and x% believe it will never happen.
Faster data retrieval, reliability and ease of management are the major reasons for implementing VTL. Half of the respondents estimate their backup window and restore time need improvement, seeking seconds for RTO (Recovery Time Objective) for part of their data. Some experience three times less unsuccessful backups with disks.
Disk-based backup is mostly used for databases. VTL is also widely used for web applications and Microsoft Exchange. Data compression and Data de-duplication are features considered very important in a VTL offering.
Backup reliability is still considered a problem by a large number of respondents. Twice as many respondents experience over 10% unsuccessful backups with tape than with disk-based backup . Tape reliability is, next to time to restore, a major problem in backup, with xxx the major culprit, and xxx a lesser problem.
Tier 4 population is the less likely to replace tape libraries with disk systems. xxx are the most eager to switch to disks followed by insurance companies. The less apt to switch are the xxx industries.
The ratio of on-line tape capacity to disk capacity averages 1 today, whereas it was about 1.5 in 2005 and 2.0 in 2004.
The major product selection criterion for a VTL product is xxx. It is deemed essential that VTL integrates with current users software and hardware, including CDP, replication and de-duplication.
But Tape is not dead
Tape remains solid, considered by many as a safety net, one that allows a gradual move to disk.
Every year, users hope for tape to disappear, but the survey shows that, half of the backed-up data is still stored on tape. The cross-over point between disk and tape, which last year was predicted to occur in 2006, is now pushed back to xxx.
Online tape capacity continues to grow, and the backup window is not, as some pretend, a thing of the past. In terms of media used for backup, it is surprising to find that non-redundant disk (JBOD) are used by a number of sites, that DLT family of tapes store as much data as LTO.
At the end of 2006, On the average x% of the backup data is performed on tape and x% on magnetic disk, and x% on optical disk. The study forecasts the evolution of distribution of data in the next two years.
While the share of SCSI goes down, ATA and mostly FC are gaining share of the backup market. X% of the population resents ATA. Reliability, data rate and seek performance are the primary reasons.
