Can you export or backup knowledge base solutions?

I don't think it is currently possible in the UI. However I believe that Freshservice are planning some updates to the solutions module this year, so potentially this will be looked at.

It is possible if you use the API:

Export folders, one at a time: https://api.freshservice.com/#view_all_solution_article

or to export everything at once you could iterate over categories and folders and then make the previously mentioned api call per folder/category pair: https://api.freshservice.com/#view_all_solution_category

Once you can do this, it would be very easy to schedule as needed.

Thanks Matthew - I'll give it a try.  
As long as I can get the solutions backed up somehow then I feel happier to commit to putting them all in Freshservice!

Try this:

$api_key = "API_KEY"

$helpdesk_url = 'https://HELPDESK_URL.freshservice.com'

function normalizePath
{
  param (
    [string]$path
  )
  return $path.Split([IO.Path]::GetInvalidFileNameChars()) -join '_'
}
$solutions = @()

$EncodedCredentials = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $api_key, $null)))
$HTTPHeaders = @{ }
$HTTPHeaders.Add('Authorization', ("Basic {0}" -f $EncodedCredentials))
$HTTPHeaders.Add('Content-Type', 'application/json')
[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.SecurityProtocolType]::Tls12

$url = $helpdesk_url + '/solution/categories.json'
$response = Invoke-WebRequest -Uri $url -Headers $HTTPHeaders | ConvertFrom-Json

$response | ForEach-Object {
  $_category = $_.category.name
  $_.category.folders
} | Select-Object id, category_id, name | ForEach-Object {
  $_url = $helpdesk_url + '/solution/categories/' + $_.category_id + '/folders/' + $_.id + '.json'
  Write-Host $_url
  $categoryResponse = Invoke-WebRequest $_url -Headers $HTTPHeaders | ConvertFrom-Json
  $categoryResponse.folder.articles | ForEach-Object {
    $_folder = $categoryResponse.folder.name
    write-host "Backing up: $($_.title)"
    $solutions += [pscustomobject]@{title = $_.title; content = $_.description; category = $_category; folder = $_folder }
  }
}

$solutions | ForEach-Object {
  $title = normalizePath($_.title)
  $category = normalizePath($_.category)
  $folder = normalizePath($_.folder)
  $path = ".\$category\$folder\"
  if (!(Test-Path $path))
  {
    New-Item -Path $path -ItemType Directory
  }
  $_.content | Out-File -FilePath ($path + "$title.html")
} 

This is a Powershell script which will export all solutions to html files in the folder structure .\<category name>\<folder name>\<article name>.html

Replace the url and api key placeholders with your own details. Note that embedded media (images,etc ) as well as attachments aren't downloaded so these would need to be exported manually as far as I can tell.

There needs to be a formalised method for this, as it stands with no ability to export, only import it is not a solution it's a lock in. 

Exporting solutions by script is ugly, also exporting without the option of exporting embedded media is an unacceptable workaround IMHO.

Freshservice's is main marketing mantra is ease of use, make this process easy please.
