AceBIT

Hi,
I was wondering how Acebackup backs up open files (Files in use). Is it safe to assume that scheduled backups won't fail if I am working on a file that Acebackup is trying to back up?

Thanks

How indeed does AceBackup take account of open files, of which there can be many?

I've been using and/or evaluation a number of other backup products (such as NTI's Shadow and SecondCopy). They all stumble a bit when they encounter open files. For example, SecondCopy seems to not copy them at all. From my perspective, having forty years as an IT technical practitioner, it should be perfectly possible to COPY any open file (not to update or delete them, of course).

So, what's the answer to this excellent question by thepyramus?

Acebackup can backup open files, since copies directly bytes from the HDD clusters assigned to a locked file.

Of course it is not a preferred method to backup an open file, since theoretically Windows can modify a file while AceBackup is copying its bits.

Good to know that open files are actually backed up. The problem could be that Windows is accessing the file during the backup and this would lead to problems. The safest way is to close all files (if possible) before starting the backup. That's at least how I use to do it.

Totally agree with the above, for files that are being held open for Update (being actively written to). Then again, even in this case it might be worth backing them up (say, some file that is gradually being appended to, where any backup might be better than none at all).

But quite often files are created quickly, then closed (small text documents, for example). After that, they are likely only ever opened only for Read (input), so surely they're worth being backed up even if open?
Cheers, Tony.
