It would appear that the aquisition of Iomega by EMC is paying is dividends by way of cool tech being added to the Iomega Range. So, as you may be aware Iomega released their new IX12 NAS box earlier this month (see previous post for more info) , which has many of the gubbins of “proper” NAS. What could this Sub £10k little box have that pips EMC and Netapps big enterprise boxes to the post ? It has an Avamar agent installed in the NAS device !!… Granted, if you don’t know what avamar is, that previous statement may have been something of an anti-climax… Let me elaborate:
- Typically what type of data contain the most commonalilty?
- Typically which type of data consumes the most storage ?
- Which type of data takes the longest time to backup ?
The answer to the question my pedigree chums.. is file data (in most cases, not all.. granted). So, Company X (The commercial division of the Xmen.. obviously), has a head office in London and a number of regional small branch offices dotted around the country. Each one of these offices is serving up user home directories and network drives from said Iomega IX12 (lets say 4TB per office).. When it comes to backing those sites up; do they back it all up to tape or disk locally, taking up time and budget on a per site basis for their backups ? Do they back it all up to disk, replicate data to a central site for DR and try and shove how ever many terrabytes down a 100MB link wondering why it takes sooo long ? nay.. After a the first full backup they only backup the block level changes over the link to their central site , allowing them to negate the requirement to backup to disk locally on their smaller regional offices.. bearing in mind that typically the daily rate of change on unstructured data is less than a percent.. nightly backups can be done quick sharp and are treated as full backups when it comes to restore, so you don’t have to run through all your incremental backups to ensure you’re up to date.
Not a bad bit of tin if you ask me..
