Hi,

we are planning take OS backup. OS has nfs mounts as weel.

Currently I am using include and exclude options with rsync but it is lengthy command where i need to include all OS realate like bin, dev, lib, root, etc etc and exclude others with *

Is there any easiest method where i can backup oS with excluding nfs file system and includin all os files.

Thanks

Put your include and exclude patterns in files. From

Code:

man rsync

Code:

            --exclude=PATTERN       exclude files matching PATTERN
            --exclude-from=FILE     read exclude patterns from FILE
            --include=PATTERN       donât exclude files matching PATTERN
            --include-from=FILE     read include patterns from FILE

If the OS is entirely in one file system, you can use the -x flag. That restricts rsync to a single file system. So, it would be something like this:

Code:

rsync -vaxAX --delete /. /mnt/nfsshare/myOSbackup/

Even if your OS is stored in a few different file systems, I'd probably go with -x flag, and use multiple rsync commands (one for each relevant filesystem in /etc/fstab).

Oh - if the OS backup is being done over nfs, it's perhaps better to "pull" from the destination server than to "push" from the source server. I find that when rsync tries to write to an nfs mount, some special files have weird permissions that can't be set reliably. But when pulling from an nfs mount to a local hard drive, the weird permissions are set just fine. Either way, though, the resulting backup works fine.
