What to choose in 2018: bareos or bacula?

Question

System administration

There is a motley fleet of servers: windows, linux, some are baremetal, some are virtualized on KVM.
You need a centralized backup solution and it's free (yes-yes).
Who worked with bacula / bareos, can you explain a couple of points?
1) which one to choose? Are both projects alive and developing in 2018?
2) what about the functional differences?
3) how are they with backup volumes (disks)? VSS support in Windows and snapshots in zfs/btrfs/lvm?
4) did not find normal information about restoring from a backup from scratch. Only a description of some crutches. Everything is bad?
And finally, is there a better alternative? (no budget for veam/acronis)

Answer 1

It's very simple, Bareos and Bacula are no better or worse than any other programs and solutions if you do not consider various scenarios of data loss, leakage or corruption.
Bareos (I won't mention Bacul anymore, although everything that has been said applies to it too) allows you to protect yourself in the following scenarios:
And the answer is: if you use Bareos, then:
Bareos makes this relatively easy to set up. All saved files are taken into account in the database, you can search and compare when a file was added, changed, where it is stored.
