Data Storage cleanup/reclaim is similar to how we manage “kinds of stuff” in our homes. We think what to keep and not to after taking the holistic decision. Time & Value will decide what is to be discarded in near future…
An All-Flash Storage array (AFA’s) gives the best performance and greater value to the business. But every GB of All-Flash Storage is at least 3 times costlier than that of mechanical drives. It is critical to perform frequent clean up of these kinds of arrays to make sure that only the mission/business critical data and deserving information should reside on All-Flash array.
From the business perspective, the concerned team needs to do the regular drills to identify then inform IT Ops to discard stale or amassed data ASAP. This requires the team to do a logical distinction of information based on value or tasks, seek approvals from respective Business Unit Owners before proceeding to do clean up.
I was looking for a simple yet powerful backup / snapshot tool which would help me in taking regular backups of my Raspberry Pi. Pi is my personal AIO server running website https://vinaybabu.in, LAMP stack, Mail server, NAS services etc…
I’ve chosen rsnapshot which is based on rsync. This tool suits perfectly for my backup / snapshot requirement and works like a charm.
Download a copy and give it a try. Happy learning and Backup-ing!!
There was a requirement came to me to capture the snapshots details on an IBM Storwize V7000 storage. so, I wrote a simple PERL script to generate HTML report and send it to the stake holders and storage team via email. I’ve used the command ‘lsfcmap’ to list the snapshot details. Using PERL I’ve captured required output in desired order and format to suit our requirements.
Please find below report generated and sent over an email (split into two images for better readability)
- Can run the script via scheduler or On-Demand
- Sorted based on descending order to list the oldest snapshots on top of the list
- Old reports are archived for future reference or troubleshooting purposes
Please let me know if you need the script to replicate for your V7K’s.
