Is this normal to see these files in /var/backups/md?

What are those huge files?

 No.  My md folder has 64kb of data in it, and it has no tmp folder.

Perhaps check the file dates - if they are old (or if no backup jobs are running) it should be safe to delete everything in /tmp

You could copy them to the data volume if you want to be very conservative.

Thanks!  I removed the tmp files... no idea why they were there, but really appreciate it.

You should have raid_config_XXXX_XX_XX_XXXXXX.tar.xz files in /var/backups/md

Has support looked at your system for some reason? Sounds like they extracted one of those files but forgot to clean up afterwards.

The compressed archive can be invaluable in a data recovery situation. So leave the tar.xz files but you can delete everything else in /var/backups/md

The files in /var/cores are core dumps. These can be useful for diagnosing why those services crashed. If they're recent you may wish to compress them e.g.

# cd /var/cores
# lzma -9 core-readynasd

and keep them around in case they're needed for troubleshooting or if they're very old you could just remove them.

/var/lib/apt/lists contains the list of available packages to install.

/var/cache/apt contains the package archive of packages that have been downloaded.

/var/log/journal contains the main log for the system (this is rotated automatically).

/var/readynasd and /var/backups/readynasd contain important databases and backups respectively. Leave these alone.

Thanks for this...

I am trying to figure out why my rsync jobs keep hanging up on each file.  It goes for a bit, then pauses, then starts up.  I am only able to copy about 200MB a day and it's driving me crazy!
