Fbackup

[ramesh_4]

My server's backup is running on fbackup. But i get some warning messages that a file is not backed up because the file was active during backup. I can see that the file was being written into by another process. Is there any way or any option for fbackup to backup an active file. Any one pls help me out?

There is no way to backup an active file. You need to kill the process which is using the file in order to get a clean backup of it. Ie. if you know what files are usually 'in use' before the backup then do an fuser -fk on the file before you start the backup, this will kill of whoever is using it enabling a good clean backup.

Hi,

I still suggest Omniback over fbackup. Omniback backs up the physical files residing on the disk regardless of whether the file is in use or not.

Because of the fbackup skipping over active files altogether ie. ignoring the physical files residing on the disk, fbackup is usually being recommended to be run in single-user mode instead of multi-user mode.

Hope this helps. Regards.

Hi,

If your disks are mirrored, you can split off one of the mirrors and back up the mirror. Also, I understand that if you have OnlineJFS, you can back up active filesystems by taking a "snapshot" of the filesystem.
