Issue with Incremental Backup of File Share

[RobL216]

We are backing up a File Share hosted on a Synolgy NAS appliance.

This share hosts files for our Marketing department and therefore are mostly Apple MAC files.

The full backup runs with a few exceptions on files that if can't open etc but other than that is seems to be fine backing up just under 900GB.

When the incremental runs though it is backing up over 900GB of data!  There is no way that our guys are chaning that much in a day so there is someting wrong somewhere.

Could it be I need to use a different backup method other than file modified date?

Any thoughts anyone?

We do not support incremental backups over shares as incremental backups require an agent running on the system concerned. So you need to be using Windows or supported Linux versions (on the device that holds the data) OR for the device to be supported by the NDMP Option (for Level based incremental backups)

Note: if you use a NAS device that can present over iSCSI then an agent on the server that accesses the iSCSI LUN would allow incrementals - but you would have to re-think your storage a bit to implement this (so easier to setup if you have not already started using the storage in production)

Thanks for the answer.

That makes perfect sense.

Thank you again.
