The disk where my os resides is about 233GB
If I created a backup for the entire disk, macrium would finish the task after hours.
Instead, I moved all programs and data (that I could) to a DATA partition and left the system (almost) alone.
In this way, I create a backup for the system partition
and the other needed partitions
(EFI system partition, microsoft reserved partition, recovery partition) only.
About 30.5 GB
The latest backup occupies about 17.7GB
and it took less than 20 minutes
(the disk is an ssd).
I included also a free partition to maintain the partition table
All of which is to say that with everything you've selected (380.52GB
), it could take you between 4 and 5 hours, or even more
And you will need around 220GB
available (or even more) for the backup.
If you don't care about that time and about that space, i.e., you have that time and that space and many more, proceed.
Otherwise, try to move some data to another (safe) place.
