Topic: flexbackup to disk on server is backing up backup files

[Pascal Van Hecke]

Hi,

I followed the instructions on http://mirror.contribs.org/smeserver/contribs/dmay/mitel/howto/flexbackup-to-disk-howto.html but instead of backing up to a client pc, I use a third hard disk on the sme server it self (other two disks in raid).

So instead of
//servername/sharename  /mnt/backup  smbfs   username=name,password=pword
in /etc/fstab
I added
/dev/hdg /mnt/backup

The script runs well, mounting and unmounting the third hard disk, but strangely enough it backs up the mounted backup disk itself, resulting in an exponentially growing file until it breaks on the 2 meg limit, and then the process continues until the disk is full with 2 meg files...

Are there any other people having this problem?

I 'll paste the mailed log here, maybe that'll give a clue.

2 meg dont you mean 2 GB limit? and this issue was dissucussed in this thread:

http://forums.contribs.org/index.php?topic=6761.msg24312#msg24312

You need to change what flexbackup is backingup so it does not included the backup mount, but that is a bit over my head, have you tryed searching the forums?

Yes, sorry, I meant  2gig instead of 2 meg.
I was simply explaining that the flexbackup is taking a backup of /mnt/backup itself, so the resulting file is doubled in sieze every time till the 2 gig limit is reached.
I simply followed the instructions in http://mirror.contribs.org/smeserver/contribs/dmay/mitel/howto/flexbackup-to-disk-howto.html, and I do not understand why I get this result.  If I check /mnt/backup on the server, it is not mounted automatically, the third disk is only mounted by the crontab process.  How can I exclude the third disk from the backup?

The flexbackup command issued is

flexbackup -fs all

which I take it to mean backup all mounted filesystems defined in flexbackup.conf.

The filesystems listed in flexbackup.conf are / and /boot.

Therefore if you are mounting something under /, then it gets backed up too. Which I take it to mean that if you mounted a CD-ROM and left it mounted when backup starts, then it probably gets backed up too ?!??

You will probably get an answer from the flexbackup list:

flexbackup-help@lists.sourceforge.net

but you'll have to join the list if you want to see the repsonce, which usually happens several minutes after you post, he's relly good like that
