Event Timeline

We can solve this problem in three ways.
Now the script (https://github.com/vyos/vyatta-op/blob/29703664633a20385a077083b4393738bdcb7409/scripts/tech-support-archive) creates up to 5 versions of support archives, after which it starts deleting the previous one. The problem is that each new version of the archives contains from 1 to 4 old archives. As a result, the archive can take up a lot of space.

Option one:
Save archives to a folder, that is not included in the folders saved by the script.

now:

DEFAULT_PATH=/opt/vyatta/etc/config/support

after:

DEFAULT_PATH=/usr/support (for example)

option two:
do not allow the script to save old versions.

now:

if (( count >= 5 )); then

after:

if (( count >= 1 )); then

option three:
combine options 1 and 2
