Files replaced with older versions not backed up
We have a scenario that we moved to an older file within our system. In a review while trying to figure out what had happened we noted that the original file was backed up but the older version we put out this morning was not. Is this by design?
The example would be that the original file in place was from 8/26/2015 and we had to replace with one from 4/19/2015. This second older file was not backed up at all.
CloudBerry Backup uses the file timestamp as an indicator of change. Otherwise, we would be forced to perform a time-consuming binary compare (hash) for each and every file on the hard drive. CloudBerry sees the modified datetime stamp as older and it does not trigger the backup. But I understand why this is an issue for you. My recommendation would be to update the file so its modification date is current. Even if we did back up the file as is, it could cause retention issues if you're using the modification date for retention. Meaning, if you kept backups for 30 days from modification date, and the older timestamp was more than 30 days ago, I don't think CloudBerry will even back it up as it would be deleted immediately from backup storage. You can change modification dates using some freely available utilities or you can test using the following command from a command prompt (
please perform test on a test file first to be sure it works for you
COPY /b FILENAME.EXT + ,,
That should update the file timestamp without any file modifications.
