Hi

a new option appears UseNBackup

but help is not very clear about it.

what is the advantage/disavantage to use it ?

according to test i pratice (very few

), it seems that the "standard" backup have a smaller size and works on backgroud whereas the nbackup seems modal ?

regards

Hi

thanks for the answer

may i ask something more ?

i read that with UseNBackup set to True, the backup can be done ONLY in the host machine.

Is it also the case with the UseNBackup set to false ? (it seems yes)

i used the the both way, the size of the backup file is totaly different
original size : 6 G
UseNBackup = true : 6 G
UseNBackup = False : <3G

why such difference ?

regards

Yes, IBCBackupService backs a database up on the host machine. This behaviour is connected with the specificity of InterBase server, and not with IBDAC.
Sizes of the backup files are different because the files have different format. You can learn more about this in the InterBase server documentation.
