Backing up

Hi everyone

we are very new to app sync and trying to implement it. As of now we are using crash consistent copy but with this my Archive Log fs is not being copied while copy back.

1. To mount Archive Log on target server while copy back what should we do?
2. should we use Hot backup mode to mount archive FS while copy back?
3. What will be the impact on source/target db if we use hot backup mode.

Thank You
