Backing Up a Catalogue, Including the Folders

[eapples]

I finally did a complete backup of my photo catalogue in Photoshop Elements 24.  I checked the backup -- the photos are there, with numeric names that bear no relationship to what's in my catalogue.  My folders that appear in the catalogue are not in the backup.  If I ever have to resort to using the backup, it's useless to me.  Maybe I don't understand the backup function in Photoshop Elements 24.

I thought that I would see the photos, with the identifiers that appear in the catalogue, as well as the folders that I used to organize the individual photos.  Did I do something wrong?

Thank you for your help.

Everything you are seeing is normal, and you did nothing wrong.  The names of the files and the path upon which they currently exist are all contained in the database file which is the heart of the Organizer.  If you ever need to restore the backup, your files will be placed in the original folder hiearchy or in a new one depending on choices that you make.  Any tagging or face recognition that you have performed will also be restored.

Thank you.  I thought about it after I posted my query -- I won't be accessing the backup as backup, only when I have to restore, and the restoration will appear as I'm used to seeing.

You are right that the concept of a backup is something different from what you are expecting: that the result would be an identical and immediately useable copy of your media files.

A backup is always the first part of a two steps process: backup then restore.

For instance you can use a zipping utility to backup a folder hierarchy. You get a compressed  .zip file  which is not useable unless you unzip (decompress, that is restore to the original state).

As Greg correctly points out, the organizer is an asset manager built on a powerful database engine which records, indexes all kind of info about your files.

The catalog itself is technically a folder containing the main database and its accessory tools and folders. It also holds a cache for your thumbnails (another sqlite database). The structure of your folders hierarchy is necessarily recorded in the catalog (folder).

The backup is also a folder, containing all the components of your catalog folder and renamed copies of all your photos and videos. It also contains a special file (backup.tly) which is another way to translate the folder organization for the restore process.

Tip: that backup.tly file is the last one recorded in the backup process. If it's lacking, that means that the backup was not correctly completed.

The purpose of the backup / restore process is mainly to solve two kinds of problems:

- the computer crached, was stolen...

- or more frequently, you want to transfer your library, photo and catalog to a new hardware.

To perform the transfer, you must obviously store the contents of both the catalog and the catalog;  You must also update the location of each media file in the catalog database to the new location (new computer, new disk/partition or new master folder).

Usual general use backup solutions can provide backups separately for the media and the catalog. They can't update the location information when you move to another disk or location.

Side note:

The other Adobe application also based on a catalog, Lightroom Classic, does not provide backup for the media files (photos and videos), only for the catalogs. You are supposed to choose your own way with other softwares. To update the contents of the database, you must have a simple folder hierarchy. Then a reconnection process is available for the database.  The reconnection feature in Elements organizer is not practical to do the same, you have to backup and restore from the organizer.

Thank you.  I gotta say -- the extra detail you provided will come in handy if I ever run into problems restoring my photos.

Using photoshop elements 2024, windows 10. 

I have 2 laptops, one is a clone of the other. I am running Photoshop Elements (PSE) 2024 on both computers. On laptop #1 my PSE catalog is: 6.21 GB,  242,173 files. I created a full backup to my external hard drive from it. The backup file on the external hard drive: size on disk: 176 GB,  234,474 Files. When I try to restore it from the backup file to the PSE on laptop #2, it fails with a message saying that I do not have enough disk space. The catalog size on laptop #2 now shows  457 GB,  1,372,044 Files!! The backup/restore process uses exactly the same SPSE software on each laptop. Clearly, something is wrong with the PSE software. No solution!!
