Shell command to tar directory excluding certain files/folders
Is there a simple shell command/script that supports excluding certain files/folders from being archived?
I have a directory that need to be archived with a sub directory that has a number of very large files I do not need to backup.
Not quite solutions:
The tar --exclude=PATTERN command matches the given pattern and excludes those files, but I need specific files & folders to be ignored (full file path), otherwise valid files might be excluded.
I could also use the find command to create a list of files and exclude the ones I don't want to archive and pass the list to tar, but that only works with for a small amount of files. I have tens of thousands.
I'm beginning to think the only solution is to create a file with a list of files/folders to be excluded, then use rsync with --exclude-from=file to copy all the files to a tmp directory, and then use tar to archive that directory.
Can anybody think of a better/more efficient solution?
EDIT: cma 's solution works well. The big gotcha is that the --exclude='./folder' MUST be at the beginning of the tar command. Full command (cd first, so backup is relative to that directory):
cd /folder_to_backup
tar --exclude='./folder' --exclude='./upload/folder2' -zcvf /backup/filename.tgz .
You can have multiple exclude options for tar so
$ tar --exclude='./folder' --exclude='./upload/folder2' -zcvf /backup/filename.tgz .
etc will work. Make sure to put --exclude before the source and destination items.
You can exclude directories with --exclude for tar.
If you want to archive everything except /usr you can use:
tar -zcvf /all.tgz / --exclude=/usr
In your case perhaps something like
tar -zcvf archive.tgz arc_dir --exclude=dir/ignore_this_dir
Possible options to exclude files/directories from backup using tar:
Exclude files using multiple patterns
tar -czf backup.tar.gz --exclude=PATTERN1 --exclude=PATTERN2 ... /path/to/backup
Exclude files using an exclude file filled with a list of patterns
tar -czf backup.tar.gz -X /path/to/exclude.txt /path/to/backup
Exclude files using tags by placing a tag file in any directory that should be skipped
tar -czf backup.tar.gz --exclude-tag-all=exclude.tag /path/to/backup
