My Canon 70D generates CR2 files. My Photoshop CC running on Windows 10 opens them using Adobe Camera Raw.

I would like to be able to upload groups of photos (albums), so that others can view, download, or print them.
I want members of each group to be restricted to only one particular album.

I can give these members a link and password or key, but I want to restrict their ability to only view, download, or print the photos.
They should not be able to view other albums, or make any changes to any album.

Note: The download ability isn't critical.

Any help or suggestions are welcome.

Lee Valley has PVC connectors for several pipe sizes. They are designed to be used to build plant covers. They offer many different configurations, plus a clip to hold fabric to the pipe. Look at their 2016 home & garden catalog, page 56.

How do I sign up?

You have the ability to check first (or last) dupes. Then delete checked dupes. Yes, it is easier on small directories.

There is a handy free program called Doublekiller. It will find files with duplicate contents, regardless of name.

Note: The processed files are different from the sooc versions.

You can then select those to be deleted.

My backed up catalogs are stored as a zip file(Lightroom Catalog.lrcat.zip).

When I use the Lightroom menu to: File/Open Catalog, and navigate to the backup folder, I get the message "No items match your search". It seems that it is looking for Lightroom Catalog.lrcat without the .zip suffix.

If I use Windows to expand the zipped file, then it is found, and I can open it. This looks like this is a new feature of Lightroom. Is it documented anywhere? The documentation that I've seen doesn't mention a zipped file. Should I be doing something different?

Then, when I open the (expanded) backed up catalog, It recognizes it as a backup, and tries to help by warning me that I may be loosing some work. It also tells me that it turned off sync.

What does this mean, and should I turn it back on to continue using this catalog?

Some older card readers can't handle 64G cards.

You mentioned two identical cards.
Do they both behave the same?
Are they really identical?

Both black and white are colors! :)

Can you elaborate on what you're having a problem with? What do you mean by 'sync"?

I have a program that will rename files within a directory to the name of the directory, appended with a sequence number.

It will recognize that multiple files have the same name but different file extensions ( IMG_378.cr2, IMG_378.jpg, IMG_378.png) and rename them with the same sequence number.

If they are in the directory named 2016-02-25 Picnic, They will be renamed 2016-02-25 Picnic 001.cr2, 2016-02-25 Picnic 001.jpg, 2016-02-25 Picnic 001.png.

If this is what you mean by 'sync' then I would be glad to share the program.

My error was in thinking that by using an external drive to transport my files between two computers, and therefore having three copies of them, that would be a safe strategy.
I will still use that for keeping the two computers in sync. I’m using Beyond Compare to mirror one directory (folder) to another. It will overwrite older files with newer files and will delete any files on the destination that have been deleted on the source, but does not remove the empty directories. I use RED (Remove Empty Directories) for that. http://www.jonasjohn.de/red.htm

However, I’ve added a true backup strategy. I use a free program is AOMEI Backupper. http://backup-utility.com It allows recovery at any increment of time.
Thanks to all responders. Here is a response to some.


Even if I were to determine what caused this problem, I can’t prevent other problems in the future. I need to have a strategy that allows me to recover when something like this happens.


The advantage of Beyond Compare and like programs (over manually copying) is that you don’t need to keep track of the changed files. The disadvantage is that any file that has changed, even accidentally, will be copied over, replacing the existing file.


Some backup programs (even though they are incremental) will only allow for the recovery of the latest version of a file. The solution is to use a backup program that allow recovery of each and every incremental backup. Generally the recovery points are indexed by date, and possibly by a comment or description.
One such free program is AOMEI Backupper. http://backup-utility.com


In your example, when the changes on C are mirrored onto K, the older (existing) files on K will be overwritten (lost).

===================================

Again, thanks to all posters. It's been enlightening!

Keep in mind that the switch itself is a resource that can be depleted. (wear out).

I looked for the incremental capability and didn't see it. I'll look again.

Thanks for your responses.

I'm using Windows 10, on a very fast machine. I'm quite competent using a computer, so powerful is more important than easy to use. Free is also nice.

I had forgotten about differential backup. Perhaps that is a good choice.

I have been backing up my photos by copying the latest versions to a backup folder on a internal drive, and to a backup folder on an external drive.

I've transferred files from my primary computer to the external drive, then from the external drive to my secondary computer. After working at the secondary computer, I've transferred files from the secondary computer to the external drive, then from the external drive back to my primary drive.

I've been using a program called Beyond Compare. It will compare the files in the source and destination folders, and copy any newer files from the source to the destination, overwriting the destination files.

The problem occurred when a file became corrupt somewhere in the process, and I didn't know it. Unfortunately, the corrupt file was propagated throughout the system.

I'm looking for a program that will backup my files using incremental backups. That is, the first time I backup, the entire contents will be copied to a file on the backup folder. After that, only the changed files will be copied to a different file on the same backup folder. Each successive backup will use a new file, containing only the files that were changed since the last backup. Hence the term "incremental"

I've looked at the program SyncBack, but it overwrites older files.

This may be a wakeup call if you're doing your backups like I was.

Does anyone have any suggestions for a program that does incremental backups?
