Failed Backup - archive bits reset?

[Matthew_Longmui]

Hi,

My query(ies) is in regards to Incremental backups.

1. It says in the admin guide that the archive bit is reset on files AFTER the backup completes (i.e. not during the backup). Is this true? Just wanted to confirm.

2. What happens if the Incremental backup fails 50% through the back up, for whatever reason - would the archive bit be reset on the 50% that was backed up successfully? Or would the archive bit not be touched because it was not a successful backup?

Thanks in advance!

the archive bit is being reset right after the file has been backed up, not after the job has finished.
That means, if your incremental backup crashes at 50%, the archive bit for all the files backed up (50 % off all files to be backed up) will be reset to 0 !
If you would rerun the same incremental backup, only the folders of the previously backed up 50% data would be backed up again - and of course the remaining 50% of data, as their archive bit has still not changed before.

Hope this helps

Hi Uz,

Just to clarify, cause it looks like you contradicted yourself (or otherwise i didnt understand):

The Inc backup fails 50% through.
The first 50% backups up fine - archive bit reset to 0
The second 50% failed to backup - archive bit still set to 1

Correct?
if so:

if i run the backup the next night, it will backup the second 50% (because the bit is still set at 1) and whatever else may have changed/created that day?

Yes, exact as you described !
(First 50 % set to 0 - second remain 1 - next INC backup only saves second 50 % plus newly changed files.)
