Possible pitfalls using FAST MIRROR

Postby rgdudley » Tue Jan 02, 2018 9:19 pm

I am just wondering what possible problems I might run into using fast mirror for backing up a external hard drive containing 30 thousand pictures. Currently I make two backups using mirror without the FAST option. I recall having had some problems using that option in the past.

Hi,

There should be no problems. The Fast Mirror will back up only new and modified files from sources. That will result in a faster backup.

I guess I am wondering if I delete some files from the source disk, will those also be deleted from the destination disk using the fast option. I think that was the problem I had in the past. I would want them to be deleted from the destination so it is an exact copy of the source.

Hi,

If you want to also remove from destination the files deleted from sources, you need to select the "Remove excluded or deleted files" option from Backup Properties->Type->Mirror.

Great. Thanks.

I also assume that any alterations made to the destination outside of backup&4all will not be noticed by b4a when using the fast option.

Hi,

Yes, that is correct. Backup4all won't monitor the destination all the time, to track any change made outside Backup4all.
It is supposed you won't manually alter the backup in destination.
