Lotus Domino

Hi all,

Could somebody help me, I deploed Sym BackupExec 12d. But my Lotus backup takes a lot of time. 330 Gb bacup more than 8 hours.

How to reduse the time of backup?
  • Reading from RAID5 will be quick, and its writing to RAID10 which is faster at writing than RAID5 for example.
    However, this could be a bottleneck with your server RAM. I see your backup server's memory is 1GB. If you can up this memory and try the backup again, you might see a speed increase. However, you'll be lucky to get backup speeds of over 400MB/m depending on the amount of traffic across your network at the time of the backup.

  • Hi Dr. Max,

    Firstly I take it you have the agent loaded, and are making use of this agent to backup Lotus Notes?
    Do you only have this issue with Lotus Notes, and can you answer these questions:

    1. Is LN on another server, and what sort of LAN connection does it have? 
    2. What is your network speed?
    3. What sort of speeds do you get with other sections of your backups?

    Laters!
  • Hi CraigV!

    It's used the Lotus agent.
    BacupExec and Lotus are two different servers.
    The speed of network - 1 Gb.
    Total : 335 560 926 011 byte, speed of job : 557,00 MB per min, time of job 11:41:52

    Thanks
  • Hi there,

    That might be about right.
    What you can look at doing is making sure your switch ports are configured to run at the full speed of the NIC in your server, and then also making sure your NICs are configured to their full speed.
    I've also put in 2 links to check out...1 will might help with improving the speed of the backups, and other explains why your backups would have slower speeds...

  • CragV,

    The usual time of Lotus backup is 8 or 9 hours. I cannot run the job earlier 23:00 and it mush stop not later 7:00.
