Do you go any errors in the event logs on the windows server that might aid with this?
does the /dwelling house/sqlback folder exist and are the permissions correct on information technology?

Thanks, At this time i did some workaround in gild to take MySQL backup using the same share.
In crontab
10 23 * * * /usr/bin/umount -a -t cifs -50
12 23 * * * /usr/bin/mountain -t cifs -o user=operator,password=mypassword //ten.10.10.30/sql /domicile/sqlback/
15 23 * * * mysqldump -u root automation > /home/sqlback/Automation_Dailybackup.sql
Pitiful, I don't retrieve its a permission issue. Once the backup procedure is completed share drive get hanged.

Are you sure the dump is completing successfully and that you are not loosing the connexion earlier information technology finishes. Would hate for yous to arrive a situation of needing the backups and observe they are corrupt or incomplete.
You might try pipage the mysqldump command to gzip for pinch in order to decrease the amount of information being transferred and salvage on storage space too.

Are y'all sure the dump is completing successfully and that you are not loosing the connection before information technology finishes. Would detest for you to get in a state of affairs of needing the backups and discover they are decadent or incomplete.

Deplorable to necro an old thread (it's still quite loftier in Google searches), only after an update I ran into some bug on an older automobile. One of the updates changed the specification with regards to version binding. We're using a very old NetApp for a couple of unimportant bits. I found that I at present take to specify the smb version when connecting to older machines based on error letters in the syslog. So essentially:
BASH
mount.cifs //server/share /mnt/mntpoint -o username =myusername,domain=ourdomain,vers= i.0 Not good I know but we're chucking the NetApp soonish.
Could be something similar in play hither.
