Managing storage for virtual servers
Server virtualization might’ve made life
Backup has been a particular headache for storage managers coping with virtual machines. Twenty-nine percent still use traditional backup methods, with a backup client installed in each VM. That number has dropped from 43% a couple of years ago as backup administrators employ alternatives such as using specialized VM options in their backup software (11%), backing up the physical server (11%) and VM-specific products (7%). Twenty percent are holding out and still using VMware Consolidated Backup (VCB) despite its being effectively shelved by VMware.
63% say their companies are using more storage with VMs than they did before.
By the numbers
- Eighteen percent say that with VMs they find they’re backing up too much data.
- For 14%, VM backup is still too complicated.
- Eleven percent say they’ve had to deploy more disk to accommodate their VMs.
- More than a third (36%) say “no problem” when it comes to VM backup.
Shops trying new backup approaches
For most shops, backup is still Job No. 1 and Headache No. 1 for a lot of them. Apparently, cutting tape is one method companies are using to streamline backup operations. Thirty-four percent say they’ll reduce their use of tape in 2012, about the same as we’ve seen the last two years. But only 15% say they’ll increase tape usage, which is the lowest number we’ve ever seen. Still, tape hasn’t left the arena just yet, as 64% say they spin off some or all backup data to tape.
On the flip side, a healthy 44% of those surveyed will increase their spending for disk-to-disk (D2D) products, with another 40% planning to spend at 2011 levels. Currently, using disk as a file system target for backups is the most popular D2D method (44%), and 27% are using data deduplication in their backup schemes. Cloud backup is also starting to play a bigger role, with 31% backing up at least some data to the cloud. Those still loathe to use cloud backup cite reluctance to send data into a public cloud (30%) and an effective current backup setup as the top reasons for eschewing cloud backup.
BYOD Alert! 21% back up tablets, 18% back up smartphones
By the numbers
- CDP may be on the rise, with 32% saying they’ll increase CDP spending in 2012.
- Forty-six percent -- the highest we’ve ever seen -- plan to increase backup dedupe spending.
- With an average of 90 slots, tape libraries are getting smaller, but 35% plan to purchase at least one library in 2012.
- Cloud backup users have an average of 12 TB of backup data in the cloud; 93% plan to increase or maintain spending levels this year.
