Time to execute a backup script to determine efficiency

Creating the tar file seems slow to me. ( I learned 2 days ago that files in zip files do not retain file permissions.)

The tar file is 15 Mb in size.

It spends around 2 seconds to create the tar file.

It is copying from a 2 Tb drive to an old Maxtor drive. (300 Mb)

Should I include some timing code with a starting time and ending time and subtract the difference?

Or I could use time.

It would tell me how long it took to execute but then how would I know if the time was appropriate?

 # This is slow, need to investigate.
    cd $DOCS
    touch  /home/andy/Documents/$( date '+%m-%d-%Y' )
    tar -cvf Ubuntu_Documents.tar *.txt *.doc *.rtf *.html *.png *.pdf *.odt *.ods *.odg *.csv *.xls *.jpg 
    ## ONLY copy file if it's newer than destination file
    ##
    /usr/bin/rsync --progress -r -u Ubuntu_Documents.tar $Backup_Directory
    # for some reason, this is not working?
    /usr/bin/rsync --progress -r -u Ubuntu_Documents.tar $Local_Backup_Dir

The utility time allows you to "time" a command, e.g.

time ls -R ~

will list total time it took to complete the command.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
