Redstone is one of Ireland\u2019s leading enterprise hardware providers in Ireland \u2013 I\u2019ll be open and admit that I\u2019m a (happy) blade and storage customer. They are running this event today in cooperation with HP Ireland. The goodie bag will in no way influence me \ud83d\ude42<\/p>\n
Today\u2019s event will focus on Data Protector, HP\u2019s backup solution, and how it can be used in a virtualised environment. The majority of the attendees are using EVA\/VMware. About 1\/4 are using Hyper-V. A couple are using Xen and a couple are using XP SAN. No one here is using Lefthand. About 1\/5 are using Data Protector for their backups.<\/p>\n
A common problem is that people rush head first into virtualisation without considering the strategy for backup.<\/p>\n
Strategies<\/u><\/strong><\/p>\n The speakers says Data Protector allows you to take both approaches to meet suitable requirements for each VM.<\/p>\n Data Protector 6.11 has VMware VCB and Hyper-V support. The core product has a license. It has the traditional bolt-on license approach. Virtualisation requires an \u201cOnline Backup\u201d license. The Zero Downtime Backup allows integration into the snapshot features of your HP storage array.<\/p>\n Note: that\u2019s probably the approach you\u2019d go with for backup of a Hyper-V CSV due to the CSV coordinator\/redirected I\/O issue with host level backups \u2013 assuming this is supported by Data Protector.<\/em><\/p>\n For storage I\/O intensive applications, Data Protector can take advantage of the ability to snapshot the targeted LUN\u2019s. You identify a LUN to backup, the SAN creates a copy, Data Protector backups up the copy while the primary continues to be used by the application\/users. This can be a partial copy for normal backup\/recovery to save storage space\/costs on the SAN. You can do a full copy of the LUN for \u201cinstant recovery\u201d, i.e. Data Protector restores file(s) from the copy of the LUN. This requires additional per TB licensing. The partial copy cannot do \u201cinstant recovery\u201d because it links back to the original storage and isn\u2019t completely independent. There\u2019s a cost for these two solutions so you save it for the mission critical, storage performance sensitive data\/applications. You can do this on a replicated partner SAN to do backups in your DR site instead of in the production site. These solutions require the VSS integrations for the storage arrays. Note that this isn\u2019t for VM snapshots.<\/p>\n Zero Time Backup and Instant Recovery can be done in VMware if<\/em> the VM uses raw device mapping (pass through disks).<\/p>\n Hyper-V <\/strong>Backup Methods<\/strong><\/u><\/p>\n I would guess the last two require passthrough disks. Might<\/em> be a solution for SQL\/Exchange VM\u2019s.<\/p>\n Really, you will end up with a combination of backup methods across the data centre, depending on VM\u2019s, applications, and backup\/recovery times\/impacts.<\/p>\n After coffee, we had some demos of VMware backups that didn\u2019t go so well for the HP speaker.<\/p>\n In summary, Data Protector gives you some HP storage integrated backup options. Be careful and ensure that servers, OS\u2019s, and applications support the backup type being used.<\/p>\n Although HP and Microsoft have announced their \u201cForefront\u201d virtualisation alliance, there\u2019s still a lot of catch up going on with regards to Hyper-V knowledge and sharing. Thanks to Redstone for organising this up in their scenic office in the Wicklow mountains \u2013 not exactly a bad place to be just after sunrise.<\/p>\n Redstone is one of Ireland\u2019s leading enterprise hardware providers in Ireland \u2013 I\u2019ll be open and admit that I\u2019m a (happy) blade and storage customer.
