Why is Skype using over 1 GB of iCloud backup data? A few weeks ago I began getting notifications warning me that I was running low on iCloud space. I didn't think much of it until I checked my iCloud backups.





To my surprise, between my iPhone and iPad, Skype was inflating the size of my iCloud backups by over 1 GB.

Even more bizarre was that Skype's documents and data were using up 600 MB less on the devices themselves. (Screenshots from Settings -> General -> Storage &amp; iCloud Usage -> Storage -> Manage Storage)

iPhone data



iPad data



The low storage warnings stopped appearing once I stated excluding Skype data from my iCloud backups, but I'm still perplexed as to why it was using so much space to begin with.

Is there a reason why Skype would need over 1GB of storage space?
Because you are saving all conversations including attachments
