Operations with backups in vaults
Backups that have no dependencies are exported without any limitations.
When exporting a transaction log backup, the data from the backup chain (a full database backup and its dependent transaction log backups up to the selected one) is copied to a single backup.
Transaction log files will be applied to the database during recovery.
Backups that have no dependencies are exported without any limitations.
When exporting an incremental mailbox backup, the data from the backup chain (a full mailbox backup and all of its incremental backups up to the selected one) is consolidated into a single backup.

Backups that have no dependencies are deleted without any limitations.
A backup that has dependencies cannot be deleted separately from all its dependent backups.
To delete a backup with dependencies manually, you should delete the entire backup chain (a full backup and all its dependent transaction log backups or incremental backups).
If you set the retention rules to delete backups older than the specified age, the outdated backup (marked with the 
icon) will be kept until all backups that depend on it also become outdated. Then, all the chain will be deleted at once.
