Backups and recovery copies
Phone backups and recovery snapshots can be some of the largest files on a Windows PC. They also may be the only copy that can restore a device or recover the computer, so SizeTrend sends the decision back to the tool that created them.
Scan the Windows drive and open the Overview pane. Recognized device backups and vendor recovery storage appear as review items, not automatic cleanup. Expand the row to see which location contributes to the total.
The measured folder size tells you where the storage went. It does not tell you whether a particular backup is still needed, current, encrypted, or replaceable.
An iPhone or iPad backup may contain settings, messages, photographs, application data, and other device state. Several devices or several retained backups can consume far more space than expected.
Open Apple Devices or iTunes and review the device name and backup date. Remove an obsolete backup there instead of deleting files from the backup folder, especially if it is the only restorable copy.
Smart Switch can keep complete local copies of Galaxy phone or tablet data, including photos, video, messages, and application information. Old device migrations can remain long after the new phone is in use.
Review the device and backup date in Smart Switch. SizeTrend does not delete these backups automatically because the folder contents alone do not prove that another good copy exists.
Dell SupportAssist System Repair can reserve snapshots used to roll the PC back after startup or performance problems. These are not ordinary duplicate files even when they are large.
Use the Dell management interface to disable System Repair or reduce its allocation if that tradeoff is acceptable. Deleting protected snapshot files directly can leave the recovery feature inconsistent.
Restore points, shadow copies, search metadata, and other protected volume data can contribute to System Volume Information. SizeTrend can identify the managed category without treating that protected folder as a normal cleanup target.
Open Tools | Manage Restore Points to review System Protection and its disk allocation. Reducing the allocation or deleting restore points gives up recovery history, so make that decision in Windows.
Before removing an old backup, confirm that the current device has a newer usable backup or that important data exists elsewhere. For PC recovery, confirm what Windows, the manufacturer, or your own imaging software can still restore.
After removing a backup through its owner, refresh the SizeTrend scan. If the folder remains large, there may be another device, another backup date, or a separate recovery product using the same drive.
Remove backups from the tool that knows what they contain.
A folder size cannot tell you whether it is the last usable recovery copy.
