  We present the analysis results of an eclipsing cataclysmic variable (CV)
V729 Sgr, based on our observations and AAVSO data. Some outburst parameters
were determined such as outburst amplitude ($A_{n}$) and recurrence time
($T_{n}$), and then the relationship between $A_{n}$ and $T_{n}$ is discussed.
A cursory examination for the long-term light curves reveals that there are
small-amplitude outbursts and dips present, which is similar to the behaviors
seen in some nova-like CVs (NLs). More detailed inspection suggests that the
outbursts in V729 Sgr may be Type A (outside-in) with a rise time $\sim1.76$ d.
Further analysis also shows that V729 Sgr is an intermediate between dwarf nova
and NLs, and we constrain its mass transfer rate to $1.59\times10^{-9} <
\dot{M}_{2} < 5.8\times10^{-9}M_{\odot}yr^{-1}$ by combining the theory for Z
Cam type stars with observations. Moreover, the rapid oscillations in V729 Sgr
were detected and analyzed for the first time. Our results indicate that the
oscillation at $\sim 25.5$ s is a true DNO, being associated with the accretion
events. The classification of the oscillations at $\sim 136$ and $154$ s as
lpDNOs is based on the relation between $P_{lpDNOs}$ and $P_{DNOs}$. Meanwhile,
the QPOs at the period of hundreds of seconds are also detected.
