Backup / Recovery question RRS feed

  • Question

  • I do a full system (bare metal) backup every night to an external HDD.  The results are in the image 

    It has always bothered me that it says "Incremental" next to C: and E:.  As I remember one would do a full backup once a week and incremental in between.  The restoration would be to restore the full then each of the incremental.  But what I have here is having selected "Full backup".  So, if tomorrow the server went up in smoke could I restore all data from the latest backup that  I have here?  I see varying totals on the backup amounts.  Am I doing something wrong with this process?

    Put another way, if drive E: failed and I restored the volume to a new hard drive would I get everything or just the files that changed the day of that backup?  I mean if I put the new HDD in and did a recover operation and picked the 3rd option "Volumes" what exactly would happen?  It states it would restore an entire "volume, such as all the data on drive C:".  So what if files were on drive E: that had not been changed in 6 months, beyond the last backup, would they still be recovered?

    Thanks.

  • Hello,

    So, if tomorrow the server went up in smoke could I restore all data from the latest backup that  I have here? 

    Answer: Yes you would be able to restore the data from the latest backup.

    Put another way, if drive E: failed and I restored the volume to a new hard drive would I get everything or just the files that changed the day of that backup?

    Answer: You would get everything.

    So what if files were on drive E: that had not been changed in 6 months, beyond the last backup, would they still be recovered?

    Answer: Yes.


    Short information about the incremental backup:

    An incremental backup is a backup that contains only the portion that has changed since the preceding backup copy was made.

    When you perform a full recovery, the restoration process would need the last full backup + all the incremental backups until the point of restoration.

    Best regards,

  • Thanks for the quick reply.

    I'm sorry, but I'm still confused.  You say above that yes, I would get everything, but then you say it would read the last full (which I don't see), then all the incremental (which I do).  Every backup properties from every day shows the same as the screen shot I posted, with varying amounts.  But they all say "incremental".

  • Open up the "Recover" wizard to check what you can recover within Windows Server Backup, you should get a better view there.

  • Hi,

    Thanks for posting in our forum!

    You can choose full backup or incremental backup for your C: in backup settings:

    For incremental backup, suppose we do incremental backup for C: then the first is full backup, and incremental backup is performed from the second backup.

    Back to your question, the premise of restoring data from incremental backup is that our source backup is not lost. In other words, if our first backup is lost, we can't restore data from incremental backup, so we always recommend full backup for backups involving important data.

    For more information about BMR and system state backup, you can see here:

    https://docs.microsoft.com/en-us/system-center/dpm/back-up-system-state-and-bare-metal?view=sc-dpm-2019

    In short, For backup of important data, we recommend that you make a full backup. And perform a schedule backup is an effective way to protect data loss and system damage.

    Compare with full backup and incremental backup, please refer to:
