Linux command: rsync
Create local backups
rsync -av --delete /Origen/ /Destino/
The code above will synchronize the contents of Directory1 to Directory2, and leave no differences between the two.
If rsync finds that Directory2 has a file that Directory1 does not, it will delete it.
If rsync finds a file that has been changed, created, or deleted in Directory1, it will reflect those same changes to Directory2.
- -a – The archive option = -rlptgoD
- -r – (as mentioned above)
-l – copy symlinks as symlinks -p – preserve permissions -t – preserve modification times -g – preserve group -o – preserve owner -D – preserve device files and special files
-v – increase verbosity -z – compress file data during the transfer -X – preserve extended attributes -A – preserve ACLs (implies -p option) -S – handle sparse files efficiently --delete – if the file is deleted from the source directory, delete it from the target directory
1. -a = recurse into directories, links (copy symlinks as symlinks), perms (preserve permissions), times (preserve modification times), group (preserve group), owner (preserve owner), preserve device files, and preserve special files.
2. -v = verbose. You can see exactly what rsync is backing up. backups.
3. –delete = This tells rsync to delete any files that are in Directory2 that aren’t in Directory1.
Remote backups
rsync -av –delete -e ssh /Origen/ user@192.168.11.21:/Destino/
or with password and port settings:
rsync -av –delete -e 'ssh -p 12345' /Origen/ user@192.168.235.137:/Destino/
