Network copy over SSH
A list of backup over ssh tips:
tar cvf – . | gzip -c -1 | ssh user@host cat ">" remotefile.gz
ssh target_address cat <localfile ">" remotefile
ssh target_address cat <localfile – ">" remotefile
cat localfile | ssh target_address cat ">" remotefile
cat localfile | ssh target_address cat – ">" remotefile
dd if=localfile | ssh target_address dd of=remotefile
ssh target_address cat <localfile "|" dd of=remotefile
ssh target_address cat – <localfile "|" dd of=remotefile
( cd SOURCEDIR && tar cf – . ) | ssh target_address "(cd DESTDIR && tar xvpf – )"
( cd SOURCEDIR && tar cvf – . ) | ssh target_address "(cd DESTDIR && cat – > remotefile.tar )"
( cd SOURCEDIR && tar czvf – . ) | ssh target_address "(cd DESTDIR && cat – > remotefile.tgz )"
( cd SOURCEDIR && tar cvf – . | gzip -1 -) | ssh target_address "(cd DESTDIR && cat – > remotefile.tgz )"
ssh target_address "( nc -l -p 9210 > remotefile & )" && cat source-file | gzip -1 – | nc target_address 9210
cat localfile | gzip -1 – | ssh target_address cat ">" remotefile.gz
ssh target_address cat remotefile > localfile
ssh target_address dd if=remotefile | dd of=localfile
ssh target_address cat "<" remotefile >localfile
ssh target_address cat "<" remotefile.gz | gunzip >localfile
