    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?

    [QUOTE=Taplin97;57269879]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

    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.
