Feature Request
Is your feature request related to a problem? Please describe:
The --gcttl is the TTL from the beginning of backup now, and users have to estimate the duration of backup + duration of other preparation before start a changefeed. However, it would be difficult to estimate the duration of backup. Once the duration is underestimated, the initial backup is wasted and must be performed again.
Describe the feature you'd like:
Define --gcttl as the TTL after backup finished. Then users only need to estimate their preparation time before start the changefeed.
Besides, --gctll defaults to 0, which means that user doesn't need a CDC, and holding GC safepoint is not necessary, for saving disk space.
Describe alternatives you've considered:
