I’m in need of some guidance when it come to backing up files which are often changing.
For now I have different backups configs running different days of different data.
User files, DB backups, media files such as photos, videos and sound recordings.
I specifically have some questions about backing up certain photos and of them the JPEG/DNG/TIFF and XMP sidecar files.
As my asset management system writes out XMP metadata to its own file but also directly into certain filetypes like jpg, dng and tiffs this filetypes constantly changes as soon as I add a label or change rating etc. And this might be done to a huge amount of files often.
The original RAW files are not changed all the time. Neither are video or sound recordings. But XMP sidecar files for them will change.
How would you recommend me setting up the backup and retention for those directories and files so that I have a good reasonable balance between back-up storage consumption, backup times etc.
Today I’m running Duplicati 3 times per week for these directories with 50MB upload size and I’m keeping the backups “Unlimited”.
The XMP and sidecars are a few KB only and there one of two of them.
The RAWs are 12-30 MB each.
The jpegs are about 5-15MB these are both generated directly in camera as well as being finalized and exported from RAWs by me.
Should I back up separate based on year instead? of running one huge set for all medias?
Backup less often?
Lower datablock size?
I could turn off the writing of XMP data into the files as well although I would like to avoid it.
