So that you can boot the system drive in old and new computers -- e.g. 
MBR is "lowest common denominator".

To boot the system when root is encrypted.

I keep records of how I partition each disk, so I can easily recreate a 
damaged partition table.  Alternatively, or in addition, there are tools 
for backing up and restoring partition tables.  The monthly images that 
I take include the partition table, boot partition, swap partition, and 
root partition.

I suggest that you look at Btrfs and/or ZFS for filesystem, metadata, 
and data integrity.  Btrfs is available in the Debian installer and can 
be used for boot, root, and data; but may require manual maintenance. 
ZFS is a package, and readily used for data; but boot and root are 
advanced use-cases.

Only you can decide what is "safe enough".

Setting up a Samba server is an ideal use-case for Debian.  So is 
setting up a Git repository.  Save up for a real server with Xeon CPU(s) 
and ECC memory (used hardware shipped to Brasil starts around US$250 on 
eBay).

Good.

Do not hope; validate.

Install Debian onto a good USB 3.0 flash drive.  Install your favorite 
troubleshooting and backup tools.  Backup your laptop as usual.  Use the 
USB Debian drive to do a restore onto alternate media.  Use the USB 
Debian drive to verify that the restore matches the original.
