Remote Vaulting
Overview
Remote vaulting involves the automatic transfer of a second copy of backup data off-site. Traditional backup and recovery solutions require a set of backup tapes to be stored off-site as a critical part of a disaster recovery strategy.
There are a number of options for remote vaulting that can also be used for remote office data protection.
Enterprise Backup software can automate the creation of a second copy of the backup sets and move it to another backup server in a remote site. The data can then be stored on a local storage device - tape, disk or VTL. The remote site can be located at a DR provider's data centre.
Data Deduplication devices are an emerging technology that can enable cost effective remote vaulting for disaster recovery purposes. In disk2disk backup solutions, deduplication substantially reduces the amount of backup data stored. Once a full copy of the data has been transferred, only the changes are sent to the second site, reducing bandwidth by as much as 99%. For some mid-market organisations this type of remote vaulting can eliminate the need for tape storage completely.
NAS Filers that combine snapshot and replication software enable copies of data to be transferred between sites to a central disk or tape storage area. Only changed data blocks are sent which substantially reduces network usage and bandwidth requirements.
Continuous Data Protection (CPD) solutions can provide cost effective remote vaulting for Windows® environments or particular applications. Working at block level and only sending changed data, it provides similar savings on network bandwidth as the deduplication and NAS filer solutions above.
