Answer: If you would like to do a level 0 dump once a week and then only back up the changes from the previous back the other six days a week, you could structure your backups in the following way:
On Sunday night, when computer activity is low, you could do a full level 0 backup of your system. This will capture all of the data on your system at that point in time.
For the rest of the week, you could do incremental backups. These backups will only capture the changes made to your system since the last backup, rather than backing up the entire system again. This will save time and storage space, as incremental backups are typically much smaller than full backups.
You could then repeat this process every week, with a full level 0 backup on Sunday night and incremental backups on the other six days of the week.
It's important to note that this is just one way to structure your backups. There are many different ways to approach backup and recovery, and the best approach will depend on your specific needs and requirements.
