i have 2 units of LS-Quad (lets call it A and B). A is now my primary unit and i have configured it to do a Complete/Differential backup to B. it is now running into its 2nd day, trying hard to backup 1.3tb of data. i tink it is going at around 300gb /day.
wat i would like to do is to alternate the use of A and B. when A completes the backup to B, i would like to use B as my primary.
question 1: if i remove the backup schedule in A and put this schedule in B to backup to A, will the backup to a differential or will it do a FULL backup again since it is now the other way round?
question 2: for complete/differential backup, or any of the backup options for that matter, how does ls identify if a file has changed? based on file date/time, size or does it keep a backup log? i assume if it goes by a backup log method, then question 1 is that it will do a FULL backup again if i reverse A and B.
question 3: if question 1 is possible, i.e. i switch from A to B, then it is also possible for me to switch from B to A anytime i want. all i need to be careful with is which way my backup is going.
thanks in advance!
