basically all of them apart from the upload bandwidth which is what the deltas address.
The amount it time to transfer the data and restore has the implications on open files, uptodate files for the backups. While restore time determines how long your server will be offline in a recovery situation.
the requirement for an agent for certain software is essential for exchange/sql etc and VSS as well
the restores are what I see as the most problematic area of an online backup system.
This is why I have discounted them up till now except for "normal" document types. |
