If snapshots are created while an application is accessing the volume, the snapshots may result from incomplete volume data and the data consistency may not be ensured.
To ensure the consistency of your snapshot data, you must stop the application that is accessing the volume in advance. After creating the snapshot, start the application again.
For example, when using the volume (master volume) as a file system such as Global File Services or ufs, unmount the volume with the umount(1M) command before creating a snapshot, and mount it with the mount(1M) command afterwards. This way, you can ensure the consistency of the snapshot data.
To create a snapshot while running the application, the file system or database system you are using to manage the data must be able to ensure data integrity.
For an example, see "6.6 Online Backup and Instant Restore through Proxy Volume."
