What is the best backup tool for Ubuntu?

Question

linux

Currently Windows Server is used as a file server. We want to install Ubuntu Server instead. And in Ubuntu already deploy samba and everything else you need.
There are about 100 users. The amount of data is approximately 2Tb.
All files should be backed up incrementally daily, and a full backup of all files should be made on weekends.
Tell me, please, which utility in Ubuntu is best suited for this? So that it can be run according to the schedule, for example, via cron.
Thank you!

Answer 1

I've been using the duplicity utility for about 6 years now. And both for backing up my laptop and for copying the servers that I support and administer.
It is simple, runs from the command line, supports encryption (GPG), backups to a specific folder, S3, ftp, etc. etc. Incremental copying with full at certain intervals, splitting copies into volumes of a given size.
A real harvester, and at the same time quite simple. For example, here is part of my laptop backup script:

duplicity \
    --full-if-older-than 3M \
    --volsize 150 \
    --exclude='**/*.pyc' \
    --exclude='**/firefox/*/cache2' \
    --exclude='**/lib/python2.7' \
    --exclude='**/.thumbnails' \
    --exclude='**/.virtualenvs' \
    --exclude='**/.virtualenv' \
    --exclude='**/thumbnails' \
    --exclude='**/.xsession-errors*' \
    --exclude='**/.PyCharm*' \
    --exclude=/home/jmv/.Private \
    --exclude=/home/jmv/.ecryptfs \
    --exclude=/home/jmv/.cache \
    --exclude=/home/jmv/.macromedia \
    --exclude=/home/jmv/.adobe \
    --exclude=/home/jmv/.nvm \
    --exclude=/home/jmv/.local/share/zeitgeist \
    --include=/etc \
    --include=/home/jmv \
    --exclude='**' \
    / $DEST

duplicity remove-older-than 12M --force $DEST

Answer 2

tar+gz+rsync

Answer 3

I take cron backups from the file server to the backup server via rsync, then on the backup server I create a snapshot of the backup directory (btrfs file system).

Answer 4

I use LuckyBackUp:
luckybackup.sourceforge.net
Easy to set up via GUI, supports both backup and sync, based on rsync.
I have been using it for 5 years already, the flight is normal.

Answer 5

I use Veeam Backup & Replication. Moreover, the free version (for legal entities too) completely covers the need for a file storage and system backup. I advise.

Answer 6

From paid I can advise acronis. Oh good stuff.

Answer 7

Any system capable of incremental backup. Whether it's the old fsbackup.pl script , or duplicity , or something else. An example with duplicity was given to you above. Using an incremental backup, you save space and can deploy a backup for a specific day with one command.
I used to use fsbackup on servers, in recent years I have been using duplicity.
