Need to reconfigure how our backups are being done

Posted on 2007-07-26
Last Modified: 2013-12-01
We are using Veritas Backup Exec 10d and backing up about 385 GB of data per night.  We are backing up to a Powervault 312T Device with 18 slots.  The backups have started to get too big as they are going into the next day's work.  What is the best method to get my data backed up?  How could I reconfigure our current H/W in order to make this happen?

    Accepted Solution

    If you are doing full backups every night, you may want to consider doing differential backups on a nightly basis and then a full once every weekend or month.  If doing a full backup on the weeked is still a problem with running over into the next day, then consider splitting the full into two backups based on directories or servers if you're doing multiple servers, and of course you would still want nightly differential backups.

    IN addition, you can try to speed things up.

    Use a separate dedicated  1 GB or faster backbone just between the backup server and the servers being backed up.

    Lastly consider getting a faster/ larger backup drive for your PowerVault.

    How fast are the backs being done ?

    Is there a speed difference between backups on different servers ?

    DO you have the latest Backup agents ?

    I hope this helps !

    1>is there room for another Tape Drive in the 132T Dell PV?If yes add another tape drive.Buy the LEO(Library expansion option) from Symantec to support the new drive.
    Split yr backups in 2 and run them concurrently
    2>Add another standalone drive (no license required)
    3>Get a JBOD and run the backups to B2D (faster) and then you can duplicate the sets on to the tape without affecting the users.

    You didnot mention whether you are running full backups OR are required to run Full backups every day

    1.  Yes, there is room for another Tape Drive [18 slots]
    2. If I did split the backups up into two and run them concurrently, wouldn't the 2nd backup still run into the next day?
    3.  Adding another stand alone drive would be good except the backups need to be taken offsite every night
    4. We're already vested wih the PV136 so that won't work right now...
    We are currently running full backups... it is not required but this practice has been in place for a number of years here.  I mentioned that we could do incrementals or differential backups...  what do you suggest?

    Depends on the type of data.

    I would try a full on weekends, and differentials during the week as a starting place.

    If it still takes too much time xonsider incrementals, but the restore will require ALL incrementals to be restored, since the last full. DIfferential only requires the full and the last differential.

    I hope this helps !

    if you add another drive and split the backups in 2 then it should not run into the other day(depends on how long its actually taking for a full backup)
    If you can then running a FULL backup once a week and Differentials thru the week should work for you
    I suggest Differentials as the restores will be faster in the event of a disaster
