Note that in this example, the directory ".snapshot" could also be either ".snapshots" or ".zfs/snapshot" depending on the filer serving your host. Just look for one of these three when you use the "ls -a" command.


Changing to my quotes directory.

[derek@novelty quotes]$ pwd
/nfshomes/derek/work/quotes

I see that i have a quote called redhat_sole_source_2007.doc.

[derek@novelty quotes]$ ls
dlt_pdf_quote2007.pdf  Quote_300086759.html         redhat_solesource.pdf
dlt_pdf_quote.pdf      Quote_353511914.html         soleSource2007.pdf
dlt_quote.pdf          Quote_367512608.html         soleSource.pdf
dy1014.xls             Quote_367884529.html         UMD_008.xls
Quote_250530976.html   redhat_sole_source_2007.doc
[derek@novelty quotes]$ ls -la redhat_sole_source_2007.doc 
-rw-r--r-- 1 derek derek 39936 Jan 23  2007 redhat_sole_source_2007.doc

I will remove it from the current file system.

[derek@novelty quotes]$ rm redhat_sole_source_2007.doc 

As you can see it no longer is there.

[derek@novelty quotes]$ ls 
dlt_pdf_quote2007.pdf  Quote_250530976.html  Quote_367884529.html   UMD_008.xls
dlt_pdf_quote.pdf      Quote_300086759.html  redhat_solesource.pdf
dlt_quote.pdf          Quote_353511914.html  soleSource2007.pdf
dy1014.xls             Quote_367512608.html  soleSource.pdf

I am going to go into the last hourly snapshot hourly.0

[derek@novelty quotes]$ cd .snapshot/hourly.0

As you can see the quote is still here.

[derek@novelty hourly.0]$ ls
dlt_pdf_quote2007.pdf  Quote_300086759.html         redhat_solesource.pdf
dlt_pdf_quote.pdf      Quote_353511914.html         soleSource2007.pdf
dlt_quote.pdf          Quote_367512608.html         soleSource.pdf
dy1014.xls             Quote_367884529.html         UMD_008.xls
Quote_250530976.html   redhat_sole_source_2007.doc

I copy it back to the original directory.

[derek@novelty hourly.0]$ cp redhat_sole_source_2007.doc /nfshomes/derek/work/quotes/

Change back to the original directory.

[derek@novelty hourly.0]$ cd /nfshomes/derek/work/quotes/

And it is back.

[derek@novelty quotes]$ ls
