Lost files in samba share - Please help me!!!

[harrisonford]

We have used a samba server to share documents in windows network since one year ago. Everything was ok until Dec 5, when inexplicably it lost some files. I think only lost the files that were used in that day. Here I listed syslog errors from one file that had gone: November Control.xlsx, but several other files were lost. I googled very much before post this and I didn't found anything consistent that could help me solve the problem. Please advise.

You're out of space or the hard drive is hooped or the network link went down, or...

My external usb 2TB HD goes read-only once in a while. Do fsck on it and see if it has problems.

Be more careful. And back-up more often if the data is important. Check out rsync. It's a good thing.

Thanks for reply, Miven.

I'm conscious it's difficult recover files because files are 1TB. I have backups but they are a little old. My major problem now is explain what happened to my boss. I can't understand the log errors. Could you help me understand it?

Thank you.
