The current Vault full backup is created in a new empty timestamp folder. The files are build up from zero on each occurrence of the backup. There is an option to create incremental backups but to keep things manageable this covers no more than a week in practice.
All files and databases are copied on each occurrence of the full backup. This is very time consuming for larger databases, very hard stressing the disk and network IO. The timestamp folder has also the disadvantage that most 3th party backups treat this as a new folder, resulting in more delays. In practice we have customers who are unable to backup their Vault in 1 weekend with the most recent hardware available today !
Some ideas around this are:
-Full backup that 'synchronizes/compares' files
-Snapshot technology
-Bit-awareness
