I've been using Linux Mint for about six months and don't want to switch back to Windows. Unfortunately, several times my system has become unusable after a download or package operation was interrupted by a power outage or crash. After rebooting, applications and commands may fail with input/output errors, the screen can freeze, and eventually the installation may disappear from the boot menu. Reinstalling Mint fixes everything, but the problem returns when another large download or upgrade is interrupted.
I've tried restoring the default Timeshift snapshots, but the same issue persisted. I'm not sure whether Timeshift needs different settings, whether I should use another backup tool, or whether the SSD is failing. Memory tests have not found any problems, and the SSD is the only major component I haven't replaced. What is the best way to create a backup that can genuinely restore my complete system, and what hardware or filesystem issues should I investigate?

A download being interrupted should not normally corrupt the entire operating system. Input/output errors, disappearing drives, and failures that worsen during large transfers strongly suggest a failing SSD, storage cable, controller, or power problem. Check the drive’s SMART data with a tool such as smartmontools, review kernel logs for I/O errors, and test with another drive or cable. Also verify the filesystem and run the manufacturer’s diagnostic tools from a live environment. Fix the underlying fault before trusting any backup or restore process.
Use separate backup plans for the operating system and personal data. Timeshift can handle system snapshots on a schedule, preferably stored on another disk. For documents, photos, and other files, use a versioned backup tool such as Back In Time or regular file copies, and keep multiple copies following a 3-2-1 approach: three copies, on two kinds of storage, with one kept elsewhere. A UPS can also help prevent filesystem damage during power failures, but it will not repair a bad SSD.
For a complete system image, Clonezilla is a solid option. Make an image of the entire disk or the relevant partitions every few months and before major upgrades, then store it on a separate physical drive. Keep a bootable Linux USB available so you can restore the image even when the installed system will not boot. Timeshift can be useful for system files and configuration, but snapshots should not be your only backup and should not live on the same failing drive.
A full image is especially useful if you want to return to the exact previous installation, but test that the image can actually be accessed or restored. A backup that has never been checked is only a hope.
The SSD is the one component I haven’t replaced, so I’ll check its SMART health and try another drive or cable. The fact that the problem happens during large downloads does make the storage device suspicious.
