An incremental backup created after a previous backup in the chain has been edited in the read/write mode will not have the changes of the edited backup

Description

An edited incremental backup is not a part of the incremental chain of archives.

If you mount an incremental backup in read/write mode, make some changes to it, then unmount it, and create a new incremental backup, the latter will not have the changes of the edited incremental backup.

This also means if you consolidate the incremental backups into full one, it will not have the changes from the edited incremental backup.

Sample scenario

1. You create a full backup of partition of partition E:

   

   The full backup is Backup #0 in Archive(1).

2. You create an incremental backup of partition F:

   

   The incremental backup is Backup #0 in Archive(2).

3. You mount in read/write mode the incremental Backup #0 of Archive (2). You make some changes to the mounted backup and then unmount it. As a result, a new incremental backup is created that contains the changes you made to mounted archive:

   

   The new edited incremental backup is Backup #1 in Archive(2).

4. Again, you create an incremental backup of partition E:

   

   The incremental backup is Backup #0 in Archive(3).

   Backup #0 of Archive(3) contains only changes that were made to partition F: and were reflected in Backup #0 of Archive(2). Backup #1 of Archive(2) is not a part of the incremental chain.
