Eric Pugh commented on SOLR-18358:
----------------------------------
so, I believe that remove that feature has been the actual plan! It's been on
my list to try and figure out the situations, so thank you.
The ref guide:
[https://solr.apache.org/guide/solr/latest/deployment-guide/collection-management.html#backup]
says:
>> Previous versions of Solr supported a different backup file format that
>> lacked the incremental support described above. Solr can still restore from
>> backups that use this old format, but creating new backups of this format is
>> not recommended and is officially deprecated. See the {{incremental}}
>> parameter below for more information.
When I look up the incremental property it says:
>> A boolean parameter allowing users to choose whether to create an
>> incremental ({{{}incremental=true{}}}) or a "full"
>> ({{{}incremental=false{}}}) backup. If unspecified, backups are done
>> incrementally by default. Incremental backups are preferred in all known
>> circumstances and "full" (i.e. non-incremental) backups are deprecated, so
>> this parameter should only be used after much consideration
So, I think that we need two things: 1) A PR that removes the code that folks
can look at, and 2) A email to the dev@ mailing list flagging this. We should
get this resolved so that future users aren't confused about the right path...
I just worked on a project that ingested backups from many different versions
of Solr, and oh boy it was not fun figuring out all the permutations in options
+ standalone versus solrcloud.
Since this would be a biggest feature change for some, maybe we want to move
this to a Solr 11 only change to give time to folks who are on the 10x branch?
If we want this on 10x, the I think we HAVE to land it on 10.1 since that is
the first version most users will actually adopt ;)

> Reporter: Eric Pugh
> Priority: Minor
>
> `CollectionAdminRequest.Backup.setIncremental(boolean)` has been deprecated
> since 9.0. Incremental backups are already the default; the deprecated
> 'full-snapshot' format is being phased out. Remove the setter and the
> full-snapshot backup code path it controls.
