Final answer:
To create a bootable USB with a Continuity Server Backup Manager ISO, you need a USB drive with at least 2 GB of storage, though it's wise to check the actual size of your ISO and possibly choose a drive with more capacity.
Step-by-step explanation:
To create a bootable USB containing your Continuity Server Backup Manager ISO, you will need a USB drive that is a minimum of 2 GB in size. This size is typically sufficient for most ISO images used for operating systems and server management tools.
However, it's important to check the actual size of the ISO file you are going to use, as some might require more space. If your ISO is larger, you will need a USB drive with a capacity greater than the ISO file.
When choosing a USB drive for this purpose, it's also a good practice to account for some additional space beyond the ISO file size for any potential overhead or additional files you may want to store.
