Regarding schedule failing

  • 1.  Regarding schedule failing

    Posted Thu August 17, 2023 12:39 PM

    Dear All,

    We need your assistance for fixing an issue. In the TSM server, one archive schedule is defined to take a weekly full backup of a log file (log.nsf) which contains the daily logging activity of our HCL Domino Mail server. The schedule is being failed due to the file being modified during the archive processing.

    This schedule has been failing for the last two years for the same cause. We also tried several times to take a manual backup at different times but did not get success.

    Below have the snapshot of taking a manual backup:

    Serialization for the archive copy groups is SHRSTatic (Shared Static).

    Please assist us to solve this. 

    Thank you all in advance.

    Have you tried to squeeze your Domino server, take a snapshot and do the backup from that snapshot?

    kind regards Martin

    No, we did not try. Actually, we have no idea about that. We will be glad if you please share the procedure.

    As you are not familiar with Domino and the steps to be taken to Backup the Databases, i suppose to use a backupagent from your Backupsoftware Vendor for Backing up Domino. As some people mentioned, the SP Data Protector is a "add On" for IBM Storage Protect Software.
    If you running a other backupsoftware pleas contact the vendor.

    kind regards
    Martin

    Dear Martin,

    Thanks for your feedback. We are sorry that we did not make you understand. Actually, we are familiar with Domino and the steps of backing up Domino databases. We don't know how to take a snapshot. If possible please provide us the steps.

    Thanks

    It has been a while since I have touched on Domino. Since the log.nsf is changing all the time you need to make sure that the data you back up are consistent. 

    SP for Domino Agent based backup is preferred since you will get a consistent backup of the database file. 

    You mention SHRSTatic which will make a try of backup 4 times before skipping the file if it is still in use. Dynamic will try one time and take a backup of whatever it can. Be aware that backing up a file that is changing is not consistent and can result in failed restores. So you need to test that the file is ok to be used by the Domino application... and on a regular basis.

    You will need to define a mgmtclass with the serialization=Dynamic on the archive copygroup. And then make an "include.archive  /local/notesdata/log.nsf classname" in the dsm.sys or inclexcl file on the baclient side.

    Snapshot of the disk can also be an option. There are different options depending on the storage system, if VM and/or if you are using LVM. This will be a crash consistent snapshot then.

    I do not know if quiesce of Domino is an option or any tools for that. You can ask HCL.

    Another question is how will you restore the file and for what purpose? Domino does not allow an overwrite of the file while it is running. I believe it is created during start of the Domino server.

    Hi,

     Can you copy the log.nsf file to a log_copy.nsf file and archive the log_copy.nsf file?

    Hi,

    In our environment we use SP Data Protector for Domino. The DP is specific to backup and restore Domino objects (e.g. nsf, ntf).

    Yes,

    You should use the SP Data Protector for Domino, but without the "START /B" which is faulty documented in the manual, as this will never return the actual success of the backups.

    Dear Tomas Dalebjörk,

    Thanks for your reply. We have two mail servers running Domino. One is being used as primary and the other one is as secondary. In our Primary mail server, Data Protection for Domino is specified but in the Secondary, data is being backed up and restored through IBM Spectrum Protect backup-archive client. We are facing a problem with archiving log.nsf database from the secondary mail server. Kindly suggest to us how can we fix this and take a backup.

    We have shared with you the defined schedule on both Primary & Secondary Mail servers for your understanding.

    Schedule on Primary Mail server:

    Schedule on Secondary Mail server:

    All except one domain users are using their webmail service through our Secondary Mail server. So it is very important for us to make sure the archive operation of log.nsf database from the Secondary Mail server is successful.

    Thank you.

    Hi

    Perhaps the Domino server is configured with circular logging, where the Domino database process locks the log file.

    You can try backing up these files using Open File support (VSS) or the older mechanism which I dont remember the name of anymore...

    But I guess your OS is of a newer version anyhow, right?
