PowerShell: backup 1C. Is everything okay?

Question

PowerShell

Good day. You need to make a backup of the 1C database. For this, I decided to use PowerShell, because. the thing, as they say, is good, and since there is no experience in this, I studied all this in parallel with writing. As a result, after a couple of days of torment, something came out. But it came out painfully bulky ...
As a result, the essence of the question is: is everything normal here? Can it be simplified? Will it let you down if something happens?

Answer 1

Firstly, sheets of logs and tons of code are not posted in the question, but placed under the cut or on the appropriate resources.
Lucky for everyone that your script is not 1000 pages long.
Secondly, it is not clear what this script has to do with backup .
At a cursory review of the script, I did not find the place where the backup is actually done.

Answer 2

I recommend that you turn to ready-made software products that perform this function
, an article on the topic https://habrahabr.ru/post/249869/
from personal experience, I store the last 3 + for the first day of the month (stored somewhere around 1.5 years) + special archives made before the update, spring global changes.

Answer 3

Veeam agent for windows. The free version in my opinion is more than suitable for you.
I use it myself at home and at work and recommend it to everyone. There is no need to reinvent the wheel, I think, in such a hackneyed question.
And in terms of scripting, yes, the script is written quite beautifully, there are a lot of comments. But, as the colleague already noted above, there is no code that actually copies the databases (well, or unloads .dt).

Answer 4

Some kind of hemorrhoid, to be honest.
Cobian Backup I use for file DB. Free, feature rich, shadow copy, runs as a service. If you want to throw out users, then at the beginning of copying, you can cram the script in the same place. I have been using it for 10 years and it works like clockwork and I had to restore the database from copies more than once - everything is buzzing.
PS Honestly, I went to this thread to understand where Power Shell is used :) Obviously, you learned how to use it well, but why you didn’t understand.
