  • Is it possible to restore files based on the file creation date (not the backup date)?
    Posted: 02-11-2014, 6:23 PM

    Hi all,

    The scenario is that we have a remote NetApp that is backing up an NFS share nightly. I want to do a nightly restore of files that were created in the last 24 hours to a development machine. Can Commvault do this? I couldn't see a way to filter the restore.

     

    Cheers,

    Paul

    Hello Paul,

    The backed up data can only be restored by its backedup date and time but not with the creation date. I dont remember or have come across any such option in commvault.

    I dont think there is any backup technology in the market which can perform restores based on creation date.

    Thanks & Regards,

    Hi Paul, hope you are well.

    What iDA are you using to backup the data?  Also is it just 'creation time' or 'modified time' which would be changes only, such as Incrementals.

    Hi Ali,

    It's being backed up via the NetApp agent. The files are logs that are saved every 5 minutes, so I presume the creation and modified dates would be identical in every case.

    In v.10 there is a filter tab on Windows iDA restores.  You might check this tab on your NAS restore and see which options are available there.  If this is not available, you could make a request via support to have this functionality added to the NAS agent.  Here is the documentation page for the Windows iDA feature: Browse and restore using filters/wildcards.

    I'm actually using a Windows agent to do the restore. Now, can I schedule a browse and restore somehow so that I can use this filter?

    Sure, here you go: Scheduling a restore.  Let us know if that does what you need to accomplish.

    Exactly, thanks jjbiv, thats option was looking to convey.

    You can schedule the restore based on these, though "creation date" isn't an option, since you know its 24 hours, pick "Yesterday" for example.

    I'm still not seeing how to do it automatically. I can browse and restore and filter, and that's fine, but I don't see how to apply that filter to a schedule. The initial back is made from a SAN agent, not a Windows agent. Maybe this isn't possible.

    Hi, Paul.  Please try this:

    • Browse using the "latest backup" option and a filter for "Modified Date Yesterday"
    • Select the folder you want to restore (this path will need to be in the backup everyday so choose as high a level in the directory structure as possible)
    • Choose "Recover All Selected"
    • Pick your restore options (these same options will be used every day so choose generic options that will work well)
    • On the "Job Initiation" tab choose "Schedule" and configure the schedule on which you wish to run the restore job (this should run after the backup for the calendar day has completed so that the relative date option above returns files from "yesterday).
    • Click "OK" and you should have a job scheduled that will run on your schedule and restore the data that was modified "yesterday" (which should always mean "yesterday" and never a particular date).
    • You can find this job in the future by right-clicking on the CommCell at the top of the "CommCell Browser" window, choose View, and Schedules.
    There are more detailed options available if you browse using an option other than "latest backup", choose the restore options you desire, and then use the "Save As Script" option and take a look at the XML file that is created.  You can have an outside scripting program change the date included in the <timeRange> section of the XML and then run the batch file on demand.  That section of the XML controls which backup is browsed.  The filter criteria is saved in the <browseFilter> section of the XML.  You could even run the batch file as a "PostBackup process" on the backup subclient and have the restore kicked off automatically once the backup completes.
    Hopefully this is a short introduction to the flexibility of CommVault for you.  There are a lot of options at your disposal here.  Try a couple and I'm sure you'll find one that will work; if not, you can always request enhancements to the product.
    Let us know how you make out and if you need anything else here.

    There is no filter tab using the SAN agent, that's the issue.

    Why yes, that would be an issue Smile  A possible option would be to restore each incremental backup in its entirity since those files would have changed (by definition of being included in the incremental backup).  With that option you could do any needed filtering of files to include on the backup subclient and then restore the entire incremental backup.  Would that work?

    No, because then I'd miss the files backed up during the weekly full backup. I'll have to work out how to submit a feature request.

    I agree that this would be a good modification request and it shouldn't be this difficult.  In the meantime, you might be able to restore the full backup, too, using the "Overwrite if file on media is newer" option (this is the default).  That should cause only the files (from the full backup) that have changed since the last incremental was restored to be restored when the restore job runs following the full backup.  That would give you the same effect as filtering for files that have changed in the last day if you are running the restore daily.  To use this, you would just need to make sure that the files were being restored to the same directory structure every day.  Perhaps there is something else I am missing here?  I wish I had a NAS agent available to test with so we could work this out for you.

    Unfortunately the reason I'm trying to do it this way is that the original backup directory is about 70GB and I don't want to keep a full copy on the target server. Our plan was to restore the last day's data, process it and then delete it from the target server.

     

    Thanks for the help, I'll mark this as resolved.

    Have you considered using replication to copy the data, either CommVault's CDR or something free like rsync or robocopy, etc?
