I'd like to make / file system backup but the problem is there are other file systems mounted under / such as:
I'd like to skip all other file systems mounted at / and only make backup of local / and not /boot, /var, /iscsi, and /mnt/cdrom etc. How do I force tar to use a single file system under Linux / UNIX / BSD operating systems?
The --one-file-system option ask the tar command not to cross mount points and stay in local file system when creating / updating archives. The syntax is as follows:
tar zcvf /path/to/file.tar.gz --one-file-system fileSystems tar zcvf /path/to/file.tar.gz --one-file-system /
In this example, make a backup of / file system to /dev/st0 without crossing file system boundaries, enter:
tar cvf /dev/st0 --one-file-system /Tweet itFacebook itGoogle+ itPDF itFound an error/typo on this page?
