+        #!/bin/sh
+
+        echo -n "root directory you want backup (/mnt/): "
+        read ROOT_DIR
+
+        echo -n "where you want to save (/home/user): "
+        read DEST_DIR
+
+        echo -n "backup name (system_name): "
+        read BCK_NAME
+
+        echo $DES_DIR
+        echo $ROOT_DIR
+
+        tar --xattrs -zcpf $DEST_DIR/$BCK_NAME-`date '+%Y-%j-%H-%M-%S'`.tar.gz \
+            --directory=$ROOT_DIR \
+            --exclude=srv \
+            --exclude=var/ports \
+            --exclude=var/run \
+            --exclude=usr/src \
+            --exclude=mnt \
+            --exclude=home \
+            --exclude=dev \
+            --exclude=run \
+            --exclude=tmp \

1.2. View content of tar

List files inside tar;

+        $tar -tvf backup.tar.gz
+

To restore is better to use first t flag and then x, + this prevents any --absolute-paths problem;

+ +

+        $ tar -ztvpf full-backup-11-November-2045.tar.gz > file.lst
+

1.3. Extract content from tar

If you want to extrat to different directory;

+        $ tar xf full-backup-11-November-2045.tar.gz --directory=/mnt
+

If path is fine, extract everything;

+        $ tar --xattrs -xpvf full-backup-11-November-2045.tar.gz
+

Extract just one file;

+        $ tar --extract --file=core.tar.gz libidn#1.32-1.pkg.tar.gz
+

1.4. Add content to tar

Only uncompressed tar can append files without having + to extract and compress again.

First create a tar with all files in the current directory;

+        $ tar cpf core.tar *.tar.gz
+

List files before appending new file and after;

+        $ tar -tvf core.tar
+        $ tar --append --file=core.tar libidn#1.32-1.pkg.tar.gz
+        $ tar -tvf core.tar
+

1.5. Remove content of tar

+        $ tar -tvf core.tar
+        $ tar --delete --file=core.tar libidn#1.32-1.pkg.tar.gz
+        $ tar -tvf core.tar
+
