Topic: restore not complete

[richard]

I'm testing SME6.03 and having a problem with backup:

Flexbackup writes 3 files to AIT-tape. One large file and two small files (as you can see in logfile) 1,2Gb in about 30 min.

Now for example: I simulate a loss of data on the server and erase some users
In this case I really want to restore the data. Restore takes about 30 sec...

Restoring from tape was successful.

For more details concerning this successful restore see:

    /var/log/messages
    /flexbackup.extract.log

BUT THE PROBLEM IS: not all the data is restored. Just a few usersettings..

Does anybody nog what the problem is? Please help me.

Thanks! Regards Richard

Look and you will find !!

What does the SME Server backup do?
The backup to desktop will compress the following directories to a file named smeserver.tgz:


/home/e-smith
/etc/e-smith/templates-custom
/etc/e-smith/templates-user-custom
/etc/ssh
/root/.ssh
/etc/passwd
/etc/shadow
/etc/group
/etc/gshadow
/etc/smbpasswd

The backup to tape will backup all filesystems, however only the files and directories in the above list will be restored. The tape backup does a level 0

• backup using a program called flexbackup.

Both methods will backup MySQL data.

• Level 0 backups of "all" assume a new tape - this will trigger tape retension and erasure.

Hello Ray,

Thanks for your reaction.

So I understand that flexbackup will not backup the entire harddisk as written in the manual? Do you know how I can make sure that ALL the files are in the backup?

Strange: The logfile says that there is 1,2Gb written on tape and that is what's on disk (and takes about 30 min. to write)

You have misunderstood my post.

The backup to tape will backup ALL filesystems, however only the files and directories in the following list will be restored. Tape backup will backup MySQL data.

/home/e-smith
/etc/e-smith/templates-custom
/etc/e-smith/templates-user-custom
/etc/ssh
/root/.ssh
/etc/passwd
/etc/shadow
/etc/group
/etc/gshadow
/etc/smbpasswd

Hope that clarifies things

PS If you want to restore files (from tape) other than those shown in the list, then you need to do that manually from the command prompt.

That is too complicated for me. (Is it?) Is there an easier way? I like to do it as the server-manager says:

The tape backup method uses a software package called flexbackup to back up your entire hard disk to tape every night. This requires a supported tape drive and a tape that is not write-protected. The backup is performed automatically at the selected time every night (with a reminder automatically e-mailed to the administrator during the day). Currently your hard disk contains 12Gb of data.
Both restore methods allow you to restore your configuration and user data files. Ideally, the restore should be performed on a freshly installed server.

Perhaps I need to restore it after a clean install?

Thanks again Ray

If you wish to use the server manager to do a restore from tape, then you do a fresh instal of the operating system first and then do the restore from tape (as the instructions say).

Hi Richard,

Do yourself a favour and forget about flexbackup.

Go to contribs.org and look for Shad Lord's Arkeia backup contrib. The JUI takes a bit of getting used to but once you get the hang of it, you will find it a lot easier to work with than having to remember command line parameters, etc. when doing restores.

thanks Kelvin,

I'll try Arkeia and keep you informed.
