**This question I don't understnad**If you do a full backup to a single tape on a Friday night and then an incremental backup to a single tape on all other days of the week (including the weekend), if a system failure occurs, what is the maximum number of tapes required to perform a full restore?

Wouldn't it be the master plus six incrementals?

lol i have no idea

sorry for all the pots new to the site

To determine the maximum number of tapes required for a full restore in this scenario, you need to understand the backup strategy and how it works.

In this case, we have a full backup on Friday night and incremental backups on all other days. Incremental backups only back up the changes since the last backup, while the full backup captures all the data.

To perform a full restore, you will need all the backup sets required to restore the data to its original state.

Let's break down the scenario:

1. Friday Night (Full Backup): One tape is used for the full backup.
2. Saturday (Incremental Backup): One tape is used for the incremental backup.
3. Sunday (Incremental Backup): One tape is used for the incremental backup.
4. Monday (Incremental Backup): One tape is used for the incremental backup.
5. Tuesday (Incremental Backup): One tape is used for the incremental backup.
6. Wednesday (Incremental Backup): One tape is used for the incremental backup.
7. Thursday (Incremental Backup): One tape is used for the incremental backup.

So, counting all the backup sets, we have the following tapes involved in the backup:

1 (Friday Full Backup) + 6 (Incremental Backups) = 7 tapes in total.

Therefore, the maximum number of tapes required for a full restore in this scenario is 7.
