Caffeine Break – 2012.01.27 – CITES TSM – Bob Booth
approx attendance: 30
Pricing:
current 99 cents per GB per year
Doing a rate and funding exercise to see if they can get the cost down. This has not been approved by governance.
Proposing a minimum 50% drop in price.
Hopefully it will be approved within a few months.
New service
The existing service is having problems. Version 5 is at its end and is at its functional limitation.
They have a second system running in parrallel running Version 6.
Hoping to be able to do more load balancing.
New features:
More robust session encryption (windows only)
Server Side deduplication – do not know who to bill for the file
Client Side server deduplication (file level)
Backup and Restores are faster
Based on db2 which is self healing
All backup media is encrypted via hardware
Questions:
Max length of retention – there is not one – it is based on policy
- Plus policy adds off site storage
- If you need different policy, contact them and they will work with you.
- Archives – keep copies
- – more expensive to maintain
- Backups versus version management
- Policies can be file based that say that certain files or folders are kept forever.
- Policies are stored on the server.
Timeline for moving to version 6 – none yet
Can migrate from one system to the other, or just start over.
What can be done to over come the challenges of using TSM
- the cost is a factor
- trouble finding the older versions
- can only see items backed up from the machine that you are at
- could there be a way to do keep files for a certain time period
- can we emulate what Time Machine does with versions / retention time
charge for dedup – charge everyone and lower the rate
VMWare native backup is being investigated and it is an extra cost for the university.
Copies can be kept in two different places – replication in real time.
secondary off site for backup and restore?
- data storage task force is looking at it
