Hello,

Please how can we compare the two backup methods and what is the difference between them (Online (hot backup)/ offline (cold backup)?

If you can shutdown or you have downtime then you can take cold backup.
Cold Backup + No Archive log mode.

If you have no downtime then you take Hot backup.

Hot Backup + Archive log mode.

Not sure why you specify cold backup + NO archive log. This can be misleading to the OP.

I was trying to indicate that the OP may take that to mean that if doing cold backups, then archive log isn't necessary.
