Hi,

I would like my system to backup my home-directory automatically regularly. I wanted to set up a script, but tar fails to create the file. It exits with the errormessage
Code:
File size limit exceeded

Which I find annoying, as this file size limit seems to be set to 2 GB. Does anyone know a workaround? The filesystem principially would support files much larger. Also the gzip version (1.3.3) would do it. tar seems to be the only problem.

regards,
airflow

personally for backups now i have started using rsync over ssh , i will be experimenting with the gzip option soon.

rsync -rcv /home/john/Documents john@viperlin:/home/john/

works great :-) and efficient too as it just updates the files that have changed using dates and checksums.

what filesystem are you backing up to?

Your question about the filesystem brought me to the solution (or at least to the real problem): I backed up to a smbfs. And there was the problem, because when I tried to backup to the same local harddisc, it worked. So I have to look at rsync or scp further...

Thx for your comment,

i assume because it was smbfs it was a windows machine running FAT32 or something :-) if you need any help on more backup methods i've seen loads on this forum alone. so find the best one for you.

Well, in fact it's from gentoo to debian! Anyway, searching in Google revealed that it seems to be a problem with the smbfs support built in to the kernel. At the moment I'm trying to find out if I have to build the backup-file first locally before sending it via scp or if I can directly pipe it through scp... I'll find out... thx again.

Just the answer for anyone who might be interested: It is not possible to pipe into scp. So a construction like
Code:
tar -c /home/user/ | scp user@host/~/blub.tar

won't work. Use ssh instead:
Code:
tar -c /home/user/ | ssh user@host 'cat > blub.tar'

will do.
