  • Is CDR right for me
    Posted: 05-27-2014, 12:15 PM

    We have a number of Windows files shares that we back up once per day. Our problem is if someone creates a for example word document after the backup has run and then deletes that word file before the next backup runs it can not be restored. I am wondering if CDR would be a good fit for us. I don't want to run incremental backups every hour because these volumes are 2 TB in size and the scan takes over an hour to complete.

    Does the replication server have to at least be the same size as the source? That is not an option either because we don't have the space.

    Jeff,  the first problem is if there isnt enough space, how would you keep all the data + the deleted files? 

    Other than that it sounds like CDR would work.

    That's one question I am asking does the CDR server only need enough space for the changes? Or does it have to be the same size as the source server and then additional space for the changes too?

    Hi Jeff, yes, destination side should have to accomodate for the growth, as there are 3 types of recovery points.  More on this here in case you haven't come accross it:

    Thanks for the input. This option is not really right for us since we would have to have an exact replica of the data and then also some additional storage for the changes. We would be better off running incrementals 4 or 5 times a day.

    I'm sharing that sentiment with you, also you could try Intellisnap, if you have the storage, however if the change of rate is 'expected/suspected' to be that fast, frequent INCs would most likely be your best option.

    If a slow scan time is making more frequent incremental backups a poor option, you could look at the optimized scan method in v.10 (formerly known as data classification in v.9).  This should make the scan phase a snap.

    You could also setup semi-frequent local shadow copies of the file server data volumes to protect files changed during the day.  These take very little space since they are copy-on-write snapshots.  End users can access the contents of these shadow copies themselves via the "Previous Versions" tab of objects on the file share.
