I'm backing up 12TB of files from MacOS to linux (synology nas) where some of the directories contain slashes.
These directories are renamed to something like 4XQVKM~Von the nas.
Is there a way to avoid this with rsync?
If not, what's the best way to rename all folders containing slashes?
While it seems the OSX allows slashes in directory/file names, linux does not. You can either rename all of the files/folders before you rsync them over, change the names after they've been rsync'd, or just accept them the way they are.
If you're looking to change the filenames before you run rsync, this thread might be useful.

I know there has been a huge discussion about this but I have not found something this specific.
Im trying to copy all .key files in /home// directory
This does not work
/usr/bin/rsync -auPA --include="*/*.key" --exclude="*" /home/* /tmp/test
This works but it copies over unwanted empty directories like /home/uname/Documents
/usr/bin/rsync -auPA --include="*/" --include="*.key" --exclude="*" /home /tmp/test
Basically what i need for rsync to do is to copy only files with .key extension and only create necessarily folders that contain .key files
I think you are looking for the -m option. From the man page:
-m, --prune-empty-dirs
This option tells the receiving rsync to get rid of empty directories from the file-list, including nested directories that
have no non-directory children. This is useful for avoiding the creation of a bunch of useless directories when the sending
rsync is recursively scanning a hierarchy of files using include/exclude/filter rules.
Note that the use of transfer rules, such as the --min-size option, does not affect what goes into the file list, and thus
does not leave directories empty, even if none of the files in a directory match the transfer rule.
Because the file-list is actually being pruned, this option also affects what directories get deleted when a delete is active.
However, keep in mind that excluded files and directories can prevent existing items from being deleted due to an exclude both
hiding source files and protecting destination files. See the perishable filter-rule option for how to avoid this.
You can prevent the pruning of certain empty directories from the file-list by using a global "protect" filter. For instance,
this option would ensure that the directory "emptydir" was kept in the file-list:
--filter ’protect emptydir/’
Here’s an example that copies all .pdf files in a hierarchy, only creating the necessary destination directories to hold the
.pdf files, and ensures that any superfluous files and directories in the destination are removed (note the hide filter of
non-directories being used instead of an exclude):
rsync -avm --del --include=’*.pdf’ -f ’hide,! */’ src/ dest
If you didn’t want to remove superfluous destination files, the more time-honored options of "--include='*/' --exclude='*'"
would work fine in place of the hide-filter (if that is more natural to you).
I have lots of directories with the same structure. A specific folder in a directory can contain a file, that I want to rename.
mv /home/*?*/domains/*?*/public/old.text /home/*?*/domains/*?*/public/new.txt
The ? can be different each time.
I tried the above, but didn't work of course.
It's on a Linux CentOS machine.
Does this do what you want?
for i in /home/*/domains/*/public/; do
echo mv "$i/old.txt" "$i/new.txt"
done
I am looking for a way to compare two folders containing source files and hard links (lets use /media/store/download and /media/store/complete as an example) and then remove orphaned files that don't exist in both folders. These files may have been renamed and may be stored in subdirectories.
I'd like to set this up on a cron script to run regularly. I just can't logically figure out myself how work the logic of the script - could anyone be so kind as to help?
Many thanks
rsync can do what you want, using the --existing, --ignore-existing, and --delete options. You'll have to run it twice, once in each "direction" to clean orphans from both source and target directories.
rsync -avn --existing --ignore-existing --delete /media/store/download/ /media/store/complete
rsync -avn --existing --ignore-existing --delete /media/store/complete/ /media/store/download
--existing says don't copy orphan files
--ignore-existing says don't update existing files
--delete says delete orphans on target dir
The trailing slash on the source dir, and no trailing slash on the target dir, are mandatory for your task.
The 'n' in -avn means not to really do anything, and I always do a "dry run" with the -n option to make sure the command is going to do what I want, ESPECIALLY when using --delete. Once you're confident your command is correct, run it with just -av to actually do the work.
Perhaps rsync is of use ?
Rsync is a fast and extraordinarily versatile file copying tool. It
can copy locally, to/from another host over any remote shell, or
to/from a remote rsync daemon. It offers a large number of options
that control every aspect of its behavior and permit very flexible
specification of the set of files to be copied. It is famous for its
delta-transfer algorithm, which reduces the amount of data sent over
the network by sending only the differences between the source files
and the existing files in the destination. Rsync is widely used for
backups and mirroring and as an improved copy command for everyday
use.
Note it has a --delete option
--delete delete extraneous files from dest dirs
which could help with your specific use case above.
You can also use "diff" command to list down all the different files in two folders.
I am rsyncing a huge (18000 files) directory, and I need use the --delete option as there is a lot of junk in the destination folder. However, the destination is under SVN revision control, so I need it to keep the .svn/ subdirectories that each directory has. I tried using the --ignore=".svn/" flag but that seems to ignore only what is on the source, and still deletes these directories on the target. Is there any way around this? Both machines are recent CentOS servers.
Thanks.
You probably want the --exclude option; --delete-excluded would allow you to do the opposite, if desired (actually delete excluded files)
Using rsync, how can I rename files when copying with the --files-from argument? I have about 190,000 files, each of which need to be renamed when copying from source to destination. I plan to have the list of files in a text file to pass to the --files-from argument.
Not entirely true... you CAN rename files enroute with rsync, but only if you rsync one file at a time, and set the --no-R --no-implied-dirs options, then explicitly set the destination name in the destination path.
But at that point, you may just want to use some other tool.
This, for example, would work:
rsync --no-R --no-implied-dirs
1.2.3.4::module/$FILENAME
/$PATH/$TOFILE/$NEWFILENAME
There is no way to arbitrarily rename files with rsync. All rsync can do is move files to a different directory.
You must use a second tool either on the sending or receiving side to rename the files.
