Re: [webmin-l] webmin remote filesystem backup with ftp

[Pat E. <mai...@pa...>]

hi jamie,

great! while you are on it, i tested a lot of backup programs which  =

support ftp transfers. as i realized, the holy grail seems to be (which =
 =

noone has found yet, i mean, it's the holy grail ;) ) to make a backup  =

(and restore btw) to a remote server without firstly creating the whole =
 =

archive locally (so that you don't need +50% free hdd space)

it could work like this:

1) start multiple splits backup
2) when backup part$1 filesize=3Dx
	2-1) pause backup
	2-2) move part$1 to remote server (then delete it)
3) goto 1)

for restore, this is what i wrote to one of the developers of a commerci=
al  =

solution (which doesn't offer it):

=3D=3Dcut--
- i have a multi-volume tgz backup on an ftp server
- i have not enough room on the target server (the one on which the  =

restoration of the data will happen) to download first all archives and =
 =

than extract them

so what can i do here? ideally i would download the first volume, do a

gunzip -c -S "" ./backup.tar.gzaa |tar -C ./ -xf -

when the first one is extracted i delete it, download the second and so =
 =

on..

but after the first archive everything comes to a halt with

gunzip: ./backup.tar.gzaa: unexpected end of file
tar: Read 8667 bytes from -
tar: Unexpected EOF in archive
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now
=3D=3Dcut--

which seems to be a limitation in gzip - maybe bzip handles it better..

anyway, thanks jamie, that you took on the problem,

PAT
