Can someone please help me urgent!!!

What do we need to know about backups/recovery/and the procedures etc??

This has come up a couple of times in past papers so could someone give me a good summary of what we need to know?

Thanks

Kind of summarise what we need to know because you've said it... backup strategies/what you need to consider when backing up, recovery plan- how to recover from a disaster, actions needed to take if it does happen, risk analysis (in the pre release so I imagine it will come up) etc. For backup, think of who/what/when/where/why, and testing the recovery of backed up data. Yeah you can expand on it c:

Backup:
-Who is responsible for backing up i.e. ICT technician in UCDM.
-A log of the backups must be kept to ensure it is in order and carried out properly.
-Time of backing up- Their main office is in Ipswich but they are located all around the world, so any time they carry out the back up would affect a few countries. But I would still say night so "fewer" activities are carried out which could be affected.
-Frequency of backup- could be done daily, weekly, fortnightly etc.
-Cost of backup- The cost of buying the media/storage space must be considered because large amounts of data would mean a large data warehouse needed- more expensive.
- What the backup will be conducted on- tape for example, where it has a vast amount of storage space, but could easily be misplaced/damaged. Disk mirroring and RAID could also be used (data stored on identical/several disks).
- Recovery of data should be tested using the backup to make sure it works.

Recovery:
-Making sure the backup strategies (above) are in place.
- Recover data in chronological order of backups (or data could corrupt).
- The equipment available to recover the data on- could be on the original site of the organisation or off site.
-The cost of recovering data might need to be considered.

I hope that's right? :biggrin:

My Steam Library is ready
Cannot wait for this to be over, almost a week later than some finishing. That "is now playing" notification is too tempting

The new system that is being developed for the merged organisations will match disaster locations with location of volunteers and equipment. Draw an entity relationship diagram to represent a relational database design that could be used.

IS THIS RIGHT ? D:[/QUOT

Can someone say what's wrong with this please

Serious question- someone please state advantages and disadvantages of UCDM using a extranet facility.

Expensive to offer the software to carry out having an Extranet, as having extranet is costly and as UCDM is a not for profit organisation, it may be hard to maintain funds for using extranet. I think that's an ok answer.

It also allows volunteers to access information on the servers that shouldn't be accessible over the internet, and upload/download files from the server

Linear- each stage is completed before moving onto the next stage with no looping back or changes made.

Iterative- project broken into stages and each is developed using a cyclic development with feedback and improvements. Parts may be developed and used before other developments.
