I'm backing up over the network, with reasonably low speeds and a few gigabytes of data. I have a small issue with Fbackup:
The backup itself, only takes up (in a test-scenario, ran a few times): ~21 minutes
But with the test afterwards, while the entire network is idle: ~34 minutes
That's +33% INCREASE in time, while I'm pretty all goes well, without a (offering more security, that the data is safely copied) CRC-check that takes up some time.
Please, make it possible for the network backups or as an Advanced setting (add a warning to it if you like, or message box "Are you really sure?"), to turn it off. And out of the few times we do a hard backup, to store the data somewhere else, we don't mind the CRC/MD5/... hash-algorythim check to be sure of our data. But +33% of the time, for a sometimes in our opinions, obsolete check... please no.
Computer/workstation are idle and have a Core2Duo. Network is limited to ~5,5 MB/sec at some locations.
