Hi Sharuzzaman,

As per my checking, the apps is not really running any DBs. Is there anything else to look at in this case?

Hi Prem,

rsync only work best with static file.

Even though you mentioned that the file (table) is not being used, but usually MySQL always refreshing the file, maybe doing indexing or something.

That is why proprietary backup software have agent for MySQL to read the binary data, and dump is as static file for the backup.

Thanks.

Hi Sharuzzaman,

Thank you for the details but isnt rsync clever enough to dump all the files? The thing is the files are not being used hence there should be likely no activities.

As for the error below: I checked the troubleshooting page and its about the $Conf{ClientTimeout} settings, which is at default set to 72000 (around 20 hrs), I have changed to 200000 but have yet to try. I hope no other implications by doing so.

Hi Prem,

MYD and MYI are files for MySQL. I believe the file is keep changing, thus BackupPC cannot determine that the size and the hash is correct, during and after the transfer.

If you really want to backup this binary database file, I would suggest that you create a static snapshot of the folder/mount point, maybe using LVM tools, provided that the file is inside an LVM logical volume.

Or, you could perform an daily dump of the MySQL table (which is a text file), then use BackupPC to backup this file. You should put exclusion for MYD and MYR file if use this method.

Thanks.
