General
Q: Can AFBackup Manager also backup clients?
A: Yes and no. The interface only lets you backup the server. You can backup clients however if you mirror the client data onto the server, if you let the client mount parts of its filesystem from the server or if you let the server mount the clients filesystem. On Windows clients this is usualy done through Samba. Since this functionality is not part of AFBackup Manager we do not support it.
Q: Do you recommend HP Ultrium-2 drives?
A: No. We did not able to resolve the single support case we had with a HP Ultrium-2
drive. I.e. we did not succeed to make the Linux system work properly with the drive.

Installation
Q: I get the following (or similar) error:
/etc/webmin/afbackup/config doesn't work: afrestore=afrestore
/usr/libexec/webmin/afbackup/config-af doesn't work: cryptkey=/etc/afbackup/cryptkey
/usr/libexec/webmin/afbackup/config doesn't work: afrestore=afrestore
A: The installation routine can not determine where afbackup was installed.
Please edit /etc/webmin/afbackup/config (or where your webmin
installtion saves its configuration) and insert the paths of the required
binaries and configuration files.
Q: I get the following (or similar) error:
Failed to install module from /usr/src/afbackup-1.7.0e.wbm :
afbackup::module_install failed : Undefined subroutine &afbackup::ui_print_header called at /usr/libexec/webmin/mscstyle3/theme.pl line 660.
A: This is a bug in the mscstyle3 module documented here (Updates to Webmin 1.160). You need to update the mscstyle3 module to stop the error message from appearing.
Usage
Q: The quantity of data has risen above the kapacity of the tapes. How do I expand the backup profile with new tapes?
A: You can not add tapes when a backup is running. That's a limitation from afbackup.
To expand a profile with new tapes you have to terminate the currently running backup
process. After which you can add a new tape:
Q: It takes ages for the AFBM status/startpage to load.
A: Possilby the request for the status of your tape drive takes very long.
If you know the status of your tapedrive anyway then you can let the
request time out. You will need to install the timeout
utility from the
TCT toolkit.
Then you can set the timeout in the configuration file
/etc/webmin/afbackup/config.
Q: I've configured AFBM to use some_number of tapes, but it allways asks me to insert the first one?
A: Afbackup will allways use the first tape that fits to save a backup. You can however use a different tape if it's got free space on it. AFBM will tell you in the mail that you receive, which tapes are free.
