Sync two mount points in the same system
HP-UX 11iv2
I am looking for a solution to keep two mount points in the same system in sync with each other.
My actual requirement is I need to move one mount point (1TB) to another volume group (for backup purpose)but without an outage (lot of updates happening currently)on the current mount point. After some point in time we will have a minimum outage and use the new MP.
Is it possible by any best method?
Note: I am not looking for BCV solution here.
Thanks,
Srini

Re: Sync two mount points in the same system
if the mount points are based on LVM and are mirrode on LVM, you could split the mirror and mount it under other mount points, and sync.

Re: Sync two mount points in the same system
Have you considered using a JFS snapshot for backup? See:

Re: Sync two mount points in the same system
Online JFS, described above has a command for splitting a file system and freezing it for update.
This product costs money.
Best method is the one that works for you.
rsync will not work for databases. It will work well for incidvidual files.
mirror/ux also costs and takes time to rebuild mirrors after a split.
