Subject:Re: Question about Backup
View as plain text  

The statement like 'I need to back up a 5T database' is not a backup strategy.  It is
intention.  There are some specifics that have to be determined to work out a strategy. 
Going from there, the backup solution can be chosen.  The examples of questions one
typically asks when determining a strategy are as follows:

1.  What is my allowed data loss in time units, f.e. hours and minutes? 
2.  What are my availability requirements for the data to be brought up, that is how
quickly I want to recover from backup?
3.  Do I need to be able to recover as of discrete points of time or as of any continuous
time range?
4.  What are my availability requirements during backups?
