You want to migrate how much data? Sooner or later, you’re going to have to move some of your data. Perhaps you’re moving to a hybrid cloud model, and need to move some offsite. Maybe it’s already out there in a third-party’s infrastructure, and the contract isn’t working out as you’d planned. Or perchance you’re being smart and replicating between two …
Oh dear, slow news day eh?
Lots of plugs, useful info being:
- data can be expensive to move
- you should have read the contract BEFORE you signed it.
- You may want to lob some tapes in the boot [trunk]
Who'd a thunk that eh??
If this is the 'new-look' El Reg, then my companion on the interwebs is on the conveyor to a slow and painful death (for the remaining staff that is...)

'“The difference between us and everyone else’s backup is that theirs is time-based, whereas we’re based on transactions,” he said. This enables the destination side of a data replication to reconstruct incremental transactions after the bulk of the data has been moved.'
Is there any transactional RDBMS offering replication that doesn't include this?
Life goes on without a Cloud or other snake oil salesman in site
If I were to suggest putting my clients data in any form of system off premises then I'd be shown the door in a flash. If they lose access to their data whe whole place stops and could take days to get fully operational again.
We are migratiing one of them from an over version of our system to another at the moment. due to a complete re-design (and a move away from crippling Oracle license costs) the thing requires a lot of work in the middle.
Woe betide any purveyos of snake-oil tht come our way in the next month. They may well leave with a sore backside.
Being low on the food chain has it's advantages, less meetings for one. Or EMC SAN's just turned up this week so the bright sparks are working out how to transition everything across from our current kit.
I will be the only Ops team member not worrying about it at all but there will be some puckered butts and crossed fingers over the next few weekends I can guarantee.
Plus there's the VMWare SRM stuff I guess, so might as well do our BCP test at the same time and tick that off.
Finally - I read someone who shares my ideas! A thumb up there.
The number of ops and devs guys that cringe when I roll out my "mickey mouse" .bat / .cmd with fast chugging data shifting capabilities using bcp, sqlcmd, sqlplus, sqlldr, mysql, sqlite3 etc etc . Meanwhile they are scratching their heads with the fancy ETL tools and their turnaround time is a matter of weeks of debugging as opposed to my mere hours, (captured, written and loaded to target)
Cloud Application services and storage are more practical for the startups, looking to capture data related to social media. The sad factor is those firms are not normally furnished with people that have the forethought for scale and optimisation leaving a less than optimal solution.
Migration is fun - thankfully we don't have to get involved in what happens after it has moved
After all - we will be moving it again soon as the accountants and shareholders finding different ways of demanding do more with less... Rinse and repeat.
