Re: [opensuse] Maximum tar file size
James, I use kdar and what I do is I select DVD 4.7 and then I reduce the size to 4.0 and it works great. Then to restore you just load the last one and select and restore. No in relation with the topic of this thread, the maximal file size depends on three variables: 1. the operating system 2. the file system 3. the tar version. You can overcome limitation in the file system piping the output. For example you can tar to stout and redirect to a file and also the stderr. tar -cp -ppPv --posix -f - /home/me/ 2 MeLogFile MeTarFile or :-) tar --create --preserve-permissions --preserve-order --absolute-names --verbose --verify --posix -f --to-stdout /home/me 2 MeTarFile.log MeTarFile.tar Restoring is the opposite xf - MeTarFile Ciao -=terry(Denver)=- On Sun, 2007-02-11 at 08:53 -0500, James Knott wrote: Bryan S.

Re: [opensuse] Maximum tar file size
James, You can unchecked slicing and it will produce a single file or select custom and it will slice it in anything you want. The only reason of slicing is to be able to fit into dvd. The 4.7 number is more virtual than real. udf will allow you to use slices 2Gb (B was comparing it with the iso)but it will not increase the size of the dvd ;-) The 4.7 is total manufactures disk capacity in decimal notation. When you use binary notation, you include the logical format (udf etc) and any error management system you can loose easily 0.5 GB. In summary manufactures total capacity do not express YOUR data capacity. Furthermore total capacity also varies according the quality of the media. So your alternatives include : double density media, lan storage or tape which is what I use for backups.

According to wikipedia the maximum file size in UDF is 16EiB (1 exbibyte = 2 to the 60th power bytes = 1,152,921,504,606,846,976 bytes = 1,024 pebibytes) However if you are burning to DVD, obviously you are constrained by the capacity of one disc.

But is there a max size limit for tar files? Can I trust tar and make one big tar file, e.g. 25 GB of my entire home directory? Hi Janus, I tried what you're contemplating here and was not at all satisfied, the principal reason being huge tarballs are sluggish to deal with when it comes time to recover something inadvertently broken or lost. I now use rsync to create mirrored snapshots of directories and partitions by scheduled script as well as via commandline whenever I need one. rsync will default to ssh2 protocol when you use it to sync a remote target to a local source. And it's reasonably easy to use, with practice. Examples: rsync -av /home/carl/ /mnt/homebak -- the 'a' is for 'archive' (means preserve all the original attributes); 'v' is verbose so you can observe progress; the trailing '/' on source means 'do not copy the directory, itself, just everything underneath it; no trailing '/' seems to be required for local targets... works for me ;-) rsync -av --delete /home/carl/ /mnt/homebak -- same as above, but truly 'syncs' a target to the source by deleting files and directories which no longer exist on the source. rsync -av /home/carl/ [EMAIL PROTECTED]:~/carlbackup/ -- will default to ssh2; will prompt for a password if needed -- add the '--delete' parameter to maintain a true 'mirror' of the source (items deleted locally since the last 'snapshot' will be deleted at the target.) Of course, YMMV and all that... hth regards, Carl -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
