Existing Folder for Backup

Hi there!

My music folder is around 90GB, and I plan to use Bvckup from now on for well, backup. I already have the folder backed up on my external drive, just that I want Bvckup to manage it from now on.  

I dont want Bvckup to create a fresh folder for 90GB, and then have it manage it. What happens when I designate to back it up that existing folder? Does  it overwrite everything again, or does it create another folder inside of it?

Yes, on first job execution it will overwrite the whole folder in most cases with default settings.

No, of course it will not overwrite the destination. I've put quite a bit of effort in making app handle backup takeovers gracefully.

What will happen on the first run is this.

It will scan both source and destination, compare them and see which files differ in either size or last-write time. It will NOT look at "created" timestamps. It will then copy over files that differ (as per above criteria) and it will also sync created times of backup copies when those are different from the source. Latter however is very quick and, obviously, doesn't involve re-copying of the file content.

In other words, if you copy a folder using Windows Explorer and then set bvckup to maintain this copy, it will do a quick adjustment of created timestamps on the first run and that's it.

Thanks, Alex!

Just tried it, and like all things with Bvckup, it worked like a frikkin charm.

Keep up the good work!

Oh, thanks for that info.

May I ask which release includes that change to make different c-times not a reason to overwrite the file by default? Seems like I've missed some details in one of changelogs.

That was in Beta 41 - https://bvckup2.com/support/forum/topic/139

Seems I got it wrong then, as from your post it seemed to me that alternative behavior only worked after user manually edits settings.ini file. Sorry for that.

Damn, this is so nice! I love your software!
Is there a way to keep a certain number of copies of modified files (in case I realize I actually need an older version)? Or does it only keep the latest copy?

Actually, I've just read your topic about file versioning, I'll keep an eye on that.

Pretty disappointed. I have several TB of data already copied to my backup drive (via robocopy) and decided to try out this app.

I expected Bvckup to be able to handle this and not re-copy all files over again. But it keeps doing it - I've even tried editing the .ini for the backup to change cdate_time and ctime_extras values, but no luck.

Here's an example file from a simulated run:

Last-modified timestamps on your source and backup copies are different. As far as the very purpose of this timestamp goes, it means that the backup copy was changed on the date stated, meaning that it's possible that it's no longer the same at its original copy, which is the reason why bvckup2 wants to recopy it.

In theory, we can add an option of NOT treating "last-modified" differences as a sign of a file change, but I am not at all convinced it's a good feature to have.
