Samba on NonStop User Manual

5. Copy the back up files to the location where supported version of NS-Samba is installed.

cd /home/smb_backup

cp smb.conf /etc/samba

cp smb.conf smbpasswd secrets.tdb passdb.tdb /etc/samba

6. Verify the internal correctness of restored files using the testparm and tdbbackup tools.

For more information on these tools, see the respective manpages.

cd /etc/samba

/usr/bin/testparm smb.conf

• Check the output message displayed on the screen for any errors.

/usr/bin/tdbbackup –v *.tdb

• Check the output message on the screen. If the .tdb files are intact, it reports the number

of records present in them.

From one Supported NS-Samba Version to Another

The NS-Samba suite provides scripts, namely, smbconf_backup.sh and smbconf_restore.sh,

to back up and restore the following default configuration and user-credential files:

• /etc/samba/smb.conf

• /etc/samba/passdb.tdb

• /etc/samba/secrets.tdb

• /etc/samba/smbpasswd

restore the configuration and user-credential files:

• Back up the files

◦ /usr/local/samba/scripts/smbconf_backup.sh

This script creates backup of the configuration and user-credential files as an archive file

and stores in the /home/.smb_backup directory: smbconfbak.<mmddyyyy>.pax,

where, mmddyyyy represents the calendar date in ‘2 Digit Month, 2 Digit Day, 4 Digit

Year’ format.

• Install the new version of NS-Samba as described in “Installing NS-Samba” (page 14).

• Restore the files

◦ /usr/local/samba/scripts/smbconf_restore.sh <back up file>

This script restores the files created by the back up script mentioned above and places

them in their default locations.

NOTE: These scripts back up and restore only the default files mentioned above. If you are using

other configuration or user credential files, such as per-user smb.conf files, you have to back

them up and restore them separately.

Fallback

To revert to a previous version of NS-Samba, complete the following steps:

1. Back up the configuration and user credential files, if required.

2. Uninstall the current version as described in “Uninstalling NS-Samba” (page 15).

3. Install the previous version of Samba.

4. Restore the configuration and user credential files, if required.
