It is weird i went thru the manual and was searching and trying, but this is what happen on Raspbian 10 with tar v.1.30:
list contents of the dir. i want to archive:
ls -lht /home/hts/.hts/tvheadend
total 1.7M
-rw------- 1 hts video 1.6M Mar 24 15:21 epgdb.v2
drwx------ 2 hts video 4.0K Mar 24 13:02 service_mapper
-rw------- 1 hts video 1.2K Mar 19 15:47 config
-rw------- 1 hts hts 41 Jan 28 19:55 superuser
drwx------ 2 hts video 4.0K Dec 18 12:47 accesscontrol
drwx------ 3 hts video 4.0K Dec 17 12:56 epggrab
drwx------ 2 hts video 4.0K Dec 17 12:52 passwd
drwx------ 5 hts video 4.0K Dec 10 17:17 input
drwx------ 4 hts video 4.0K Nov 26 23:38 channel
drwx------ 2 hts video 4.0K Nov 26 23:09 bouquet
drwx------ 3 hts video 4.0K Nov 26 23:09 dvr
drwx------ 2 hts video 4.0K Nov 26 23:09 profile
create archive:
tar -pcf /home/hts/.hts/tvheadend_backup.tar -C /home/hts/.hts/ tvheadend
remove original dir.
extract archive:
tar -pxf /home/hts/.hts/tvheadend_backup.tar
list dir. contents:
ls -lht /home/hts/.hts/tvheadend
total 20K
drwx------ 2 hts video 4.0K Mar 24 16:02 bouquet
drwx------ 3 hts video 4.0K Mar 24 16:02 dvr
drwx------ 3 hts video 4.0K Mar 24 16:02 input
drwx------ 2 hts video 4.0K Mar 24 16:02 profile
-rw------- 1 hts video 1.2K Mar 24 16:02 config
you can see that not all items was extracted. And the archive contains missing items likely:
tar --list -f /home/hts/.hts/tvheadend_backup.tar|grep service_mapper
tvheadend/service_mapper/
tvheadend/service_mapper/config
i tried to assign -vv to the tar extract command, and it shown like extracting was done:
drwx------ hts/video 0 2020-03-24 13:02 tvheadend/service_mapper/
-rw------- hts/video 146 2020-03-24 13:02 tvheadend/service_mapper/config
yet the item is not in the directory as shown above.
