#369 Backup continuously fails

[Dan Santoni]

A very very promising product btw, hoping I can make it work with your help. Thanks.

F.Y.I. The Target drive referred to below ("VERBATIM") is a FAT32 formatted USB drive. I am able to write to it using rsync ok so currently don't suspect it of being at fault but happy to be corrected on that.

OS = Ubuntu Linux 10.10 Maverick Meerkat
Java 1.6.0.24
Executing Areca via GUI and selecting "Incremental". Backup worked fine when I included only /bin and /.log (as an experiment. Then I incrementally added the extra folders listed below and it began failing with "Caused by: java.io.FileNotFoundException: /media/VERBATIM/Media Center backup/ArecaBkup/1242070071/chk0/dev/.udev/db/block:fd0 (Invalid argument)" error (details below).

Am using zip64 compression at level 9 and splitting the archive at 50meg allowing 4 chars for the archive names (using these criteria to eliminate previous errors which caused the backup to fail due to too many files in the archive).

Backup config xml

</target>

I repeatedly get the following error;

Hi

I'm not surprised that backup fails on your /dev directory, as it contains "device" files. Those files cannot be handled by Areca, which only handles standard files, pipes and symbolic links.

BTW, don't you have any warning about a "metadata accessor" issue on Areca's startup ?

[Dan Santoni]

Hi Aventin, thanks. I'm new to Linux so while I'm not sure I understand why yet, I do understand that I should exclude /dev from the backup.
I don't get any errors on startup at all but given my inexperience, I may not be looking in all the right places. Certtainly there are no idiot box messages issued through the UI.
Anyhow, it may be some time before I can experiment further but thanks for the quick response.

[Dan Santoni]

Closed as problem appears to be user error. Thanks
