CommVault 11 and VMware – ‘Virtualize Me’ Restores

Virtualize Me is a really useful feature that I’ve not had the requirement to use until recently. For any number of reasons, most companies still have actual Physical Hosts running normal workloads. They may not have been virtualized for a similar number of reasons. That’s life. I found myself with a requirement to convert a […]

CommVault and VMware – VSA Backup Filtering options

     There’s always been a number of ways to apply filters to VM’s and disks. It could be done at the Backup-Set or Sub-client level. This is a little bit clunky and can lead to unnecessary VM’s being backed up.  If you’re using a Capacity based licence, this is obviously not optimal. Space is […]

CommVault – Software Updates via HTTP/HTTPS

This is an early release feature that was slipped in without much fanfare. If you installed your CommCell using or after Version 11 SP5, you’ll be quietly downloading CommVault updates over HTTPS. For many of us though, our CommCells have evolved over various upgrades and downloads would be using FTP. While this has generally been […]

CommVault – Upgrade DDB to Transactional Mode

The deduplication databases (DDB) are arguably the most important component in an efficient and fast CommVault environment. If you’ve ever had a Media Agent fail unexpectedly before the DDB’s were able to gracefully shutdown, you’d be well aware the the restore and rebuild times can be very long. In Version 11, there have been improvements […]

CommVault v10 SP14 – Issue with Synthetic Full Backups

I recently upgraded my CommCell from v10 SP13 to SP14. As usual, the upgrade was easy. Centrally deployed, no issues. The next set of scheduled fulls kicked off a few days later, and soon after there appeared to be an issue with Synthetic Full backups. In the Job Controller they appeared to be normal. Throughput […]

CommVault – The need for speed, pt 1

Speed and performance is an important capability of a Data Protection solution. Most people logically attribute this to being able to finish all tasks in a defined “window“. I’ve used CommVault for a long time and it’s one of my all time fav’s. It truly does “what it says on the box”.  I’ve also been […]

Commvault Simpana – Automating DBMaintenance utility execution with qlogin and Powershell

Running the dbmaintenance utility regularly is a great way to get the Commcell database in ‘primo shape. Over time, data is aged, clients are reconfigured/deleted and this can all add up to indexes getting out of date, oversized tables etc. It’s recommended to do a Full DBMAINTENANCE operation every 6 months, as per CommVault latest […]

VMware ESXi CBT Bug – Your data may be at risk

Changed Block Tracking (CBT) is a great feature introduced in ESXi 4.0, that effectively brought incremental backup technology to our virtual machines. Third parties were able to leverage this so backups would only require the processing of blocks that have changed rather than all blocks. This saved inordinate amounts of time, data and effort while allowing […]
